4 Documentation to do: (any release a little bit at a time)
5 - Document running a test version.
6 - Document query file format.
7 - Document static linking
8 - Document problems with Verify and pruning.
9 - Document how to use multiple databases.
10 - For FreeBSD typical /dev/nrsa0 and for mtx /dev/pass1
11 - VXA drives have a "cleaning required"
12 indicator, but Exabyte recommends preventive cleaning after every 75
14 - Lookup HP cleaning recommendations.
15 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
18 Testing to do: (painful)
19 - that ALL console command line options work and are always implemented
20 - blocksize recognition code.
21 - multiple simultaneous Volumes
22 - Test if rewind at end of tape waits for tape to rewind.
24 - Test not zeroing Autochanger slot when it is wrong.
26 - Figure out how to use ssh or stunnel to protect Bacula communications.
29 - Currently in mount.c:236 the SD simply creates a Volume. It should have
30 explicit permission to do so. It should also mark the tape in error
32 - The bsr for Dan's job has file indexes covering the whole range rather
33 than only the range contained on the volume.
34 Constrain FileIndex to be within range for Volume.
35 - Make sure all restore counters are working correctly in the FD.
36 - SD Bytes Read is wrong.
37 - Configure mtx-changer to have correct path to mtx.
38 - Look at ALL higher level routines that call block.c to be sure
39 they don't expect something in errmsg.
41 - Fix Verify VolumeToCatalog to use BSRs -- it is broken.
43 - Use switch() in backup.c and restore.c in FD instead of giant if statement.
44 - Investigate doing RAW backup of Win32 partition.
45 - Add JobName= to VerifyToCatalog so that all verifies can be done at the end.
46 - Add thread specific data to hold the jcr -- send error messages from
47 low level routines by accessing it and using Jmsg().
48 - Default duration with no qualifier is sec should be 1 day
49 - Find a solution for the multiple FileSet problem (when it is changed). Add date?
50 - Cancel waiting for Client connect in SD if FD goes away.
51 - Testing Tibs job erred and hung director on Storage resource. This was
52 because there were a whole pile of jobs hanging around in the SD
53 waiting for a connection from the FD that was never coming.
54 - Make restore more robust in counting error and not immediately bailing
55 out. Also print error message once, but try to continue.
56 - Add code to check that blocks are sequential on restore.
57 - Should Bacula make an Append tape as Purged when purging?
58 - Possibly update all client records at startup.
60 - Add Progress command that periodically reports the progress of
62 - Implement "Reschedule OnError=yes interval=nnn times=xxx"
63 - One block was orphaned in the SD probably after cancel.
64 - Add all command line arguments to "update", e.g. slot=nn volStatus=append, ...
66 - Implement argc/argv for daemon command line scanning using table driven
68 - Implement table driven single argc/argv scanner to pickup all arguments.
69 Much like xxx_conf.c scan table.
70 keyword, handler(store_routine), store_address, code, flags, default.
72 - Examine Bare Metal restore problem (a FD crash exists somewhere ...).
73 - Test multiple simultaneous Volumes
74 - Document FInclude ...
75 - Implement timeout in response() when it should come quickly.
76 - Implement console @echo command.

79 - Implement single pane restore (much like the Gftp panes).
80 - Implement Automatic Mount even in operator wait.
81 - Implement create "FileSet"?
82 - Implement Release Device in the Job resource to unmount a drive.
83 - Implement Acquire Device in the Job resource to mount a drive,
84 be sure this works with admin jobs so that the user can get
85 prompted to insert the correct tape. Possibly some way to say to
86 run the job but don't save the files.
87 - Implement all command line args on run.
88 - Implement command line "restore" args.
89 - Implement "restore current select=no"
90 - Fix watchdog pthread crash on Win32 (this is pthread_kill() Cygwin bug)
91 - Implement "scratch pool" where tapes are defined and can be
92 taken by any pool that needs them.
93 - Implement restore "current system", but take all files without
94 doing selection tree -- so that jobs without File records can
96 - Make | and < work on FD side.
97 - Pass prefix_links to FD.
98 - Implement a M_SECURITY message class.
99 - Implement disk spooling. Two parts: 1. Spool to disk then
100 immediately to tape to speed up tape operations. 2. Spool to
101 disk only when the tape is full, then when a tape is hung move
103 - From Phil Stracchino:
104 It would probably be a per-client option, and would be called
105 something like, say, "Automatically purge obsoleted jobs". What it
106 would do is, when you successfully complete a Differential backup of a
107 client, it would automatically purge all Incremental backups for that
108 client that are rendered redundant by that Differential. Likewise,
109 when a Full backup on a client completed, it would automatically purge
110 all Differential and Incremental jobs obsoleted by that Full backup.
111 This would let people minimize the number of tapes they're keeping on
112 hand without having to master the art of retention times.
113 - Implement a relocatable bacula.spec
114 - Allow multiple Storage specifications (or multiple names on
115 a single Storage specification) in the Job record. Thus a job
116 can be backed up to a number of storage devices.
117 - Implement dump/print label to UA
118 - Add prefixlinks to where or not where absolute links to FD.
119 - Look at Python for a Bacula scripting language -- www.python.org
120 - Issue message to mount a new tape before the rewind.
121 - Simplified client job initiation for portables.
122 - If SD cannot open a drive, make it periodically retry.
123 - Implement LabelTemplate (at least first cut).
124 - Add more of the config info to the tape label.
125 - Implement a Mount Command and an Unmount Command where
126 the users could specify a system command to be performed
127 to do the mount, after which Bacula could attempt to
128 read the device. This is for Removeable media such as a CDROM.
129 - Most likely, this mount command would be invoked explicitly
130 by the user using the current Console "mount" and "unmount"
131 commands -- the Storage Daemon would do the right thing
132 depending on the exact nature of the device.
133 - As with tape drives, when Bacula wanted a new removable
134 disk mounted, it would unmount the old one, and send a message
135 to the user, who would then use "mount" as described above
136 once he had actually inserted the disk.
138 - Make some way so that if a machine is skipped because it is not up
139 that Bacula will continue retrying for a specified period of time --
141 - If tape is marked read-only, then try opening it read-only rather than
142 failing, and remember that it cannot be written.
143 - Refine SD waiting output:
144 Device is being positioned
145 > Device is being positioned for append
146 > Device is being positioned to file x
148 - Figure out some way to estimate output size and to avoid splitting
149 a backup across two Volumes -- this could be useful for writing CDROMs
150 where you really prefer not to have it split -- not serious.
151 - Add RunBeforeJob and RunAfterJob to the Client program.
152 - Have SD compute MD5 or SHA1 and compare to what FD computes.
153 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
154 actual data on the Volume and compare it.
155 - Implement FileOptions (see end of this document)
156 - Implement Bacula plugins -- design API
157 - Make bcopy read through bad tape records.
158 - Fix read_record to handle multiple sessions.
159 - Program files (i.e. execute a program to read/write files).
160 Pass read date of last backup, size of file last time.
161 - Add Signature type to File DB record.
162 - Make Restore report an error if FD or SD term codes are not OK.
163 - CD into subdirectory when open()ing files for backup to
164 speed up things. Test with testfind().
165 - Priority job to go to top of list.
166 - Find out why Full saves run slower and slower (hashing?)
167 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
168 - Implement some way for the Console to dynamically create a job.
169 - Restore to a particular time -- e.g. before date, after date.
170 - Solaris -I on tar for include list
171 - Prohibit backing up archive device (findlib/find_one.c:128)
172 - Need a verbose mode in restore, perhaps to bsr.

176 - Check if we can increase Bacula FD priorty in Win2000
177 - Make sure the MaxVolFiles is fully implemented in SD
178 - Check if both CatalogFiles and UseCatalog are set to SD.
179 - Need return status on read_cb() from read_records(). Need multiple
180 records -- one per Job, maybe a JCR or some other structure with
181 a block and a record.
182 - Figure out how to do a bare metal Windows restore
183 - Possibly add email to Watchdog if drive is unmounted too
184 long and a job is waiting on the drive.
185 - Use read_record.c in SD code.
186 - Why don't we get an error message from Win32 FD when bootstrap
187 file cannot be created for restore command?
188 - When Marking a file in Restore that is a hard link, also
189 mark the link so that the data will be reloaded.
190 - Restore program that errors in SD due to no tape reports
191 OK incorrectly in output.
192 - After unmount, if restore job started, ask to mount.
193 - Convert all %x substitution variables, which are hard to remember
194 and read to %(variable-name). Idea from TMDA.
195 - Add JobLevel in FD status (but make sure it is defined).
196 - Make Pool resource handle Counter resources.
197 - Remove NextId for SQLite. Optimize.
198 - Move all SQL statements into a single location.
199 - Add UA rc and history files.

224 - Add keyword search to show command in Console.
225 - Fix Win2000 error with no messages during startup.
226 - Events : tape has more than xxx bytes.

252 - Implement Restore FileSet=
253 - Create a protocol.h and protocol.c where all protocol messages
255 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
256 - Timout a job or terminate if link goes down, or reopen link and query.
257 - Find general solution for sscanf size problems (as well
258 as sprintf. Do at run time?
259 - Concept of precious tapes (cannot be reused).
260 - Make bcopy copy with a single tape drive.
261 - Permit changing ownership during restore.
263 - Autolabel should be specified by DIR instead of SD.
264 - Find out how to get the system tape block limits, e.g.:
265 Apr 22 21:22:10 polymatou kernel: st1: Block limits 1 - 245760 bytes.
266 Apr 22 21:22:10 polymatou kernel: st0: Block limits 2 - 16777214 bytes.
269 - AutoScan (check checksum of tape)
270 - Format command = "format /dev/nst0"
274 - Seek resolution (usually corresponds to buffer size)
275 - EODErrorCode=ENOSPC or code
276 - Partial Read error code
277 - Partial write error code
278 - Nonformatted read error
279 - Nonformatted write error
280 - WriteProtected error
284 - IgnoreCloseErrors=yes
294 - FD sends unsaved file list to Director at end of job (see
296 - File daemon should build list of files skipped, and then
297 at end of save retry and report any errors.
298 - Write a Storage daemon that uses pipes and
299 standard Unix programs to write to the tape.
301 - Need something that monitors the JCR queue and
302 times out jobs by asking the deamons where they are.
303 - Enhance Jmsg code to permit buffering and saving to disk.
304 - device driver = "xxxx" for drives.
305 - restart: paranoid: read label fsf to
306 eom read append block, and go
307 super-paranoid: read label, read all files
308 in between, read append block, and go
309 verify: backspace, read append block, and go
310 permissive: same as above but frees drive
311 if tape is not valid.
313 - Ensure that /dev/null works
314 - Need report class for messages. Perhaps
315 report resource where report=group of messages
316 - enhance scan_attrib and rename scan_jobtype, and
317 fill in code for "since" option
318 - Director needs a time after which the report status is sent
319 anyway -- or better yet, a retry time for the job.
320 Don't reschedule a job if previous incarnation is still running.
321 - Some way to automatically backup everything is needed????
322 - Need a structure for pending actions:
324 - termination status (part of buffered msgs?)
326 Read, Write, Clean, Delete
327 - Login to Bacula; Bacula users with different permissions:
328 owner, group, user, quotas
329 - Store info on each file system type (probably in the job header on tape.
330 This could be the output of df; or perhaps some sort of /etc/mtab record.
333 - Design at hierarchial storage for Bacula. Migration and Clone.
334 - Implement FSM (File System Modules).
335 - Identify unchanged or "system" files and save them to a
336 special tape thus removing them from the standard
337 backup FileSet -- BASE backup.
338 - Audit M_ error codes to ensure they are correct and consistent.
339 - Add variable break characters to lex analyzer.
340 Either a bit mask or a string of chars so that
341 the caller can change the break characters.
342 - Make a single T_BREAK to replace T_COMMA, etc.
343 - Ensure that File daemon and Storage daemon can
344 continue a save if the Director goes down (this
345 is NOT currently the case). Must detect socket error,
346 buffer messages for later.
347 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
348 - Add ability to backup to two Storage devices (two SD sessions) at
349 the same time -- e.g. onsite, offsite.
350 - Add the ability to consolidate old backup sets (basically do a restore
351 to tape and appropriately update the catalog). Compress Volume sets.
352 Might need to spool via file is only one drive is available.
353 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
354 someway to do so with every volume that has less than x% valid
358 Migration: Move a backup from one Volume to another
359 Clone: Copy a backup -- two Volumes
361 Bacula Migration is based on Jobs (apparently Networker is file by file).
363 Migration triggered by:
367 Highwater mark (keep total size)
371 Bacula Projects Roadmap
373 last update 8 May 2003
375 Item 1: Multiple simultaneous Jobs. (done)
376 Done -- Restore part needs better implementation to work correctly
377 Also, it needs considerable testing
379 What: Permit multiple simultaneous jobs in Bacula.
381 Why: An enterprise level solution needs to go fast without the
382 need for the system administrator to carefully tweak
383 timing. Based on the benchmarks, during a full
384 backup, NetWorker typically hit 10 times the bandwidth to
385 the tape compared to Bacula--largely. This is probably due to
386 running parallel jobs and multi-threaded filling of buffers
387 and writing them to tape. This should also make things work
388 better when you have a mix of fast and slow machines backing
391 Notes: Bacula was designed to run multiple simultaneous jobs. Thus
392 implementing this is a matter of some small cleanups and
396 Item 2: Make the Storage daemon use intermediate file storage to buffer data.
397 Deferred -- not necessary yet.
399 What: If data is coming into the SD too fast, buffer it to
400 disk if the user has configured this option.
402 Why: This would be nice, especially if it more or less falls out
403 when implementing (1) above. If not, it probably should not
404 be given a high priority because fundamentally the backup time
405 is limited by the tape bandwidth. Even though you may finish a
406 client job quicker by spilling to disk, you still have to
407 eventually get it onto tape. If intermediate disk buffering
408 allows us to improve write bandwidth to tape, it may make
411 Notes: Whether or not this is implemented will depend upon performance
412 testing after item 1 is implemented.
415 Item 3: Write the bscan program -- also write a bcopy program.
418 What: Write a program that reads a Bacula tape and puts all the
419 appropriate data into the catalog. This allows recovery
420 from a tape that is no longer in the database, or it allows
421 re-creation of a database if lost.
423 Why: This is a fundamental robustness and disaster recovery tool
424 which will increase the comfort level of a sysadmin
425 considering adopting Bacula.
427 Notes: A skeleton of this program already exists, but much work
428 needs to be done. Implementing this will also make apparent
429 any deficiencies in the current Bacula tape format.
432 Item 4: Implement Base jobs.
434 What: A base job is sort of like a Full save except that you
435 will want the FileSet to contain only files that are unlikely
436 to change in the future (i.e. a snapshot of most of your
437 system after installing it). After the base job has been run,
438 when you are doing a Full save, you can specify to exclude
439 all files saved by the base job that have not been modified.
441 Why: This is something none of the competition does, as far as we know
442 (except BackupPC, which is a Perl program that saves to disk
443 only). It is big win for the user, it makes Bacula stand out
444 as offering a unique optimization that immediately saves time
447 Notes: Big savings in tape usage. Will require more resources because
448 the e. DIR must send FD a list of files/attribs, and the FD must
449 search the list and compare it for each file to be saved.
452 Item 5: Implement Label templates
454 What: This is a mechanism whereby Bacula can automatically create
455 a tape label for new tapes according to a detailed specification
456 provided by the user.
458 Why: It is a major convenience item for folks who use automated label
461 Notes: Bacula already has a working form of automatic tape label
462 creation, but it is very crude. The design for the complete
463 tape labeling project is already documented in the manual.
466 Item 6: Write a regression script.
467 Done -- Continue to expand its testing.
469 What: This is an automatic script that runs and tests as many features
470 of Bacula as possible. The output is compared to previous
471 versions of Bacula and any differences are reported.
473 Why: This is an enormous help in preventing introduction of new
474 errors in parts of the program that already work correctly.
476 Notes: This probably should be ranked higher, it's something the typical
477 user doesn't see. Depending on how it's implemented, it may
478 make sense to defer it until the archival tape format and
479 user interface mature.
482 Item 7: GUI for interactive restore
483 Item 8: GUI for interactive backup
485 What: The current interactive restore is implemented with a tty
486 interface. It would be much nicer to be able to "see" the
487 list of files backed up in typical GUI tree format.
488 The same mechanism could also be used for creating
489 ad-hoc backup FileSets (item 8).
491 Why: Ease of use -- especially for the end user.
493 Notes: Rather than implementing in Gtk, we probably should go directly
494 for a Browser implementation, even if doing so meant the
495 capability wouldn't be available until much later. Not only
496 is there the question of Windows sites, most
497 Solaris/HP/IRIX, etc, shops can't currently run Gtk programs
498 without installing lots of stuff admins are very wary about.
499 Real sysadmins will always use the command line anyway, and
500 the user who's doing an interactive restore or backup of his
501 own files will in most cases be on a Windows machine running
505 Item 9: Add SSL to daemon communications.
506 Inprogress as of version 1.31.
508 What: This provides for secure communications between the daemons.
510 Why: This would allow doing backup across the Internet without
511 privacy concerns (or with much less concern).
513 Notes: The vast majority of near term potential users will be backing up
514 a single site over a LAN and, correctly or not, they probably
515 won't be concerned with security, at least not enough to go to
516 the trouble to set up keys, etc. to screw things down. We suspect
517 that many users genuinely interested in multi-site backup
518 already run some form of VPN software in their internetwork
519 connections, and are willing to delegate security to that layer.
522 Item 10: Define definitive tape format.
525 What: Define that definitive tape format that will not change
526 for the next millennium.
528 Why: Stability, security.
530 Notes: See notes for item 11 below.
533 Item 11: New daemon communication protocol.
535 What: The current daemon to daemon protocol is basically an ASCII
536 printf() and sending the buffer. On the receiving end, the
537 buffer is sscanf()ed to unpack it. The new scheme would
538 be a binary format that allows quick packing and unpacking
539 of any data type with named fields.
541 Why: Using binary packing would be faster. Named fields will permit
542 error checking to ensure that what is sent is what the
543 receiver really wants.
545 Notes: These are internal improvements in the interest of the
546 long-term stability and evolution of the program. On the one
547 hand, the sooner they're done, the less code we have to rip
548 up when the time comes to install them. On the other hand, they
549 don't bring an immediately perceptible benefit to potential
550 users. Item 10 and possibly item 11 should be deferred until Bacula
551 is well established with a growing user community more or
552 less happy with the feature set. At that time, it will make a
553 good "next generation" upgrade in the interest of data
559 ======================================================
561 It is somewhat like a Full save becomes an incremental since
562 the Base job (or jobs) plus other non-base files.
564 - New BaseFile table that contains:
565 JobId, BaseJobId, FileId (from Base).
566 i.e. for each base file that exists but is not saved because
567 it has not changed, the File daemon sends the JobId, BaseId,
568 and FileId back to the Director who creates the DB entry.
569 - To initiate a Base save, the Director sends the FD
570 the FileId, and full filename for each file in the Base.
571 - When the FD finds a Base file, he requests the Director to
572 send him the full File entry (stat packet plus MD5), or
573 conversely, the FD sends it to the Director and the Director
574 says yes or no. This can be quite rapid if the FileId is kept
575 by the FD for each Base Filename.
576 - It is probably better to have the comparison done by the FD
577 despite the fact that the File entry must be sent across the
579 - An alternative would be to send the FD the whole File entry
580 from the start. The disadvantage is that it requires a lot of
581 space. The advantage is that it requires less communications
583 - The Job record must be updated to indicate that one or more
585 - At end of Job, FD returns:
586 1. Count of base files/bytes not written to tape (i.e. matches)
587 2. Count of base file that were saved i.e. had changed.
588 - No tape record would be written for a Base file that matches, in the
589 same way that no tape record is written for Incremental jobs where
590 the file is not saved because it is unchanged.
591 - On a restore, all the Base file records must explicitly be
592 found from the BaseFile tape. I.e. for each Full save that is marked
593 to have one or more Base Jobs, search the BaseFile for all occurrences
595 - An optimization might be to make the BaseFile have:
601 This would avoid the need to explicitly fetch each File record for
602 the Base job. The Base Job record will be fetched to get the
603 VolSessionId and VolSessionTime.

616 A few days ago, a Bacula user who is backing up to file volumes and
617 using compression asked if it was possible to suppress compressing
618 all .gz files since it was a waste of CPU time. Although Bacula
619 currently permits using different options (compression, ...) on
620 a directory by directory basis, it cannot do it on a file by
621 file basis, which is clearly what was desired.
623 Proposed Implementation:
624 To solve this problem, I propose the following:
626 - Add a new Director resource type called FileOptions.
628 - The FileOptions resource will have records for all
629 options that can currently be specified on the Include record
630 (in a FileSet). Examples below.
632 - The FileOptions resource will permit an exclude option as well
633 as a number of additional options.
635 - The heart of the FileOptions resource is the ability to
636 supply any number of ApplyTo records which specify POSIX
637 regular expressions. These ApplyTo regular expressions are
638 applied to the fully qualified filename (path and all). If
639 one matches, then the FileOptions will be used.
641 - When an ApplyTo specification matches an included file, the
642 options specified in the FileOptions resource will override
643 the default options specified on the Include record.
645 - Include records will be modified to permit referencing one or
646 more FileOptions resources. The FileOptions will be used
647 in the order listed on the Include record and the first
648 one that matches will be applied.
650 - Options (or specifications) currently supplied on the Include
651 record will be deprecated (i.e. removed in a later version a
652 year or so from now).
654 - The Exclude record will be deprecated as the same functionality
655 can be obtained by using an Exclude = yes in the FileOptions.
658 The following records can appear in the FileOptions resource. An
659 asterisk preceding the name indicates a feature not currently
663 - Compression= (GZIP, ...)
664 - Signature= (MD5, SHA1, ...)
666 - OneFs= (yes/no) - remain on one filesystem
667 - Recurse= (yes/no) - recurse into subdirectories
668 - Sparse= (yes/no) - do sparse file backup
669 - *Exclude= (yes/no) - exclude file from being saved
670 - *Reader= (filename) - external read (backup) program
671 - *Plugin= (filename) - read/write plugin module
674 - verify= (ipnougsamc5) - verify options
677 - replace= (always/ifnewer/ifolder/never) - replace options currently
679 - *Writer= (filename) - external write (restore) program
683 Currently options specifying compression, MD5 signatures, recursion,
684 ... of a FileSet are supplied on the Include record. These will now
685 all be collected into a FileOptions resource, which will be
686 specified on the Include in place of the options. Multiple FileOptions
687 may be specified. Since the FileOptions contain regular expressions
688 that are applied to the full filename, this will give the ability
689 to specify backup options on a file by file basis to whatever level
698 Include = compression=GZIP signature=MD5 {
707 Include = FileOptions=Opts {
718 That's a lot more to do the same thing, but it gives the ability to
719 apply options on a file by file basis. For example, suppose you
720 want to compress all files but not any file with extensions .gz or .Z.
721 You could do so as follows:
725 Include = FileOptions=NoCompress FileOptions=Opts {
733 ApplyTo = /*.?*/ # matches all files
738 # Note multiple ApplyTos are ORed
739 ApplyTo = /*.gz/ # matches .gz files */
740 ApplyTo = /*.Z/ # matches .Z files */
743 Now, since the NoCompress FileOptions is specified first on the
744 Include line, any *.gz or *.Z file will have an MD5 signature computed,
745 but will not be compressed. For all other files, the NoCompress will not
746 match, so the Opts options will be used which will include GZIP
750 - Is it necessary to provide some means of ANDing regular expressions
751 and negation? (not currently planned)
753 e.g. ApplyTo = /*.gz/ && !/big.gz/
755 - I see that Networker has a "null" module which, if specified, does not
756 backup the file, but does make an record of the file in the catalog
757 so that the catalog will reflect an exact picture of the filesystem.
758 The result is that the file can be "seen" when "browsing" the save
759 sets, but it cannot be restored.
761 Is this really useful? Should it be implemented in Bacula?
764 After implementing the above, the user will be able to specify
765 on a file by file basis (using regular expressions) what options are
766 applied for the backup.
769 =============================================
771 ==========================================================
773 For each Incremental job that is run, there may be files that
774 were found but not saved because they were locked (this applies
775 only to Windows). Such a system could send back to the Director
776 a list of Unsaved files.
778 - New UnSavedFiles table that contains:
782 - Then in the next Incremental job, the list of Unsaved Files will be
783 feed to the FD, who will ensure that they are explicitly chosen even
784 if standard date/time check would not have selected them.
785 =============================================================
