Kern's ToDo List
- 12 November 2006
+ 27 April 2007
Major development:
Project Developer
======= =========
Document:
+- !!! Cannot restore two jobs a the same time that were
+ written simultaneously unless they were totally spooled.
- Document cleaning up the spool files:
db, pid, state, bsr, mail, conmsg, spool
- Document the multiple-drive-changer.txt script.
- Document more precisely how to use master keys -- especially
for disaster recovery.
+Professional Needs:
+- Migration from other vendors
+ - Date change
+ - Path change
+- Filesystem types
+- Backup conf/exe (all daemons)
+- Backup up system state
+- Detect state change of system (verify)
Priority:
+- Please mount volume "xxx" on Storage device ... should also list
+ Pool and MediaType in case user needs to create a new volume.
+- Implement wait_for_sysop() message display in wait_for_device(), which
+now prints warnings too often.
+
+- the director seg faulted when I omitted the pool directive from a
+job resource. I was experimenting and thought it redundant that I had
+specified Pool, Full Backup Pool. and Differential Backup Pool. but
+apparently not. This happened when I removed the pool directive and
+started the director.
+
+- On restore add Restore Client, Original Client.
+01-Apr 00:42 rufus-dir: Start Backup JobId 55, Job=kernsave.2007-04-01_00.42.48
+01-Apr 00:42 rufus-sd: Python SD JobStart: JobId=55 Client=Rufus
+01-Apr 00:42 rufus-dir: Created new Volume "Full0001" in catalog.
+01-Apr 00:42 rufus-dir: Using Device "File"
+01-Apr 00:42 rufus-sd: kernsave.2007-04-01_00.42.48 Warning: Device "File" (/tmp) not configured to autolabel Volumes.
+01-Apr 00:42 rufus-sd: kernsave.2007-04-01_00.42.48 Warning: Device "File" (/tmp) not configured to autolabel Volumes.
+01-Apr 00:42 rufus-sd: Please mount Volume "Full0001" on Storage Device "File" (/tmp) for Job kernsave.2007-04-01_00.42.48
+01-Apr 00:44 rufus-sd: Wrote label to prelabeled Volume "Full0001" on device "File" (/tmp)
+
+- Add Where: client:/.... to restore job report.
+- Ensure that each device in an Autochanger has a different
+ Device Index.
+- Add Catalog = to Pool resource so that pools will exist
+ in only one catalog -- currently Pools are "global".
+- Look at sg_logs -a /dev/sg0 for getting soft errors.
+- btape "test" command with Offline on Unmount = yes
+
+ This test is essential to Bacula.
+
+ I'm going to write one record in file 0,
+ two records in file 1,
+ and three records in file 2
+
+ 02-Feb 11:00 btape: ABORTING due to ERROR in dev.c:715
+ dev.c:714 Bad call to rewind. Device "LTO" (/dev/nst0) not open
+ 02-Feb 11:00 btape: Fatal Error because: Bacula interrupted by signal 11: Segmentation violation
+ Kaboom! btape, btape got signal 11. Attempting traceback.
+
+- Ensure that moving a purged Volume in ua_purge.c to the RecyclePool
+ does the right thing.
+- Why doesn't @"xxx abc" work in a conf file?
+- Figure out some way to "automatically" backup conf changes.
+- Add the OS version back to the Win32 client info.
+- Restarted jobs have a NULL in the from field.
+- Modify SD status command to indicate when the SD is writing
+ to a DVD (the device is not open -- see bug #732).
+- Look at the possibility of adding "SET NAMES UTF8" for MySQL,
+ and possibly changing the blobs into varchar.
- Check if gnome-console works with TLS.
- Ensure that the SD re-reads the Media record if the JobFiles
does not match -- it may have been updated by another job.
- Look at moving the Storage directive from the Job to the
Pool in the default conf files.
-- Test FIFO backup/restore -- make regression
- Doc items
- Test Volume compatibility between machine architectures
- Encryption documentation
- GUI
- Admin
- Management reports
+ - Add doc for bweb -- especially Installation
- Look at Webmin
http://www.orangecrate.com/modules.php?name=News&file=article&sid=501
- Performance
- Despool attributes in separate thread
- Database speedups
- Embedded MySQL
+ - Check why restore repeatedly sends Rechdrs between
+ each data chunk -- according to James Harper 9Jan07.
+ - Building the in memory restore tree is slow.
- Features
- Better scheduling
- Full at least once a month, ...
- Incremental backup -- rsync, Stow
-
-
For next release:
- Look at mondo/mindi
- Don't restore Solaris Door files:
.move transfer device=xxx fromslot=yyy toslot=zzz

- It appears to me that you have run into some sort of race
condition where two threads want to use the same Volume and they
were both given access. Normally that is no problem. However,
=== Done
-- Make sure that all do_prompt() calls in Dir check for
- -1 (error) and -2 (cancel) returns.
-- Fix foreach_jcr() to have free_jcr() inside next().
- jcr=jcr_walk_start();
- for ( ; jcr; (jcr=jcr_walk_next(jcr)) )
- ...
- jcr_walk_end(jcr);
-- A Volume taken from Scratch should take on the retention period
- of the new pool.
-- Correct doc for Maximum Changer Wait (and others) accepting only
- integers.
-- Implement status that shows why a job is being held in reserve, or
- rather why none of the drives are suitable.
-- Implement a way to disable a drive (so you can use the second
- drive of an autochanger, and the first one will not be used or
- even defined).
-- Make sure Maximum Volumes is respected in Pools when adding
- Volumes (e.g. when pulling a Scratch volume).
-- Keep same dcr when switching device ...
-- Implement code that makes the Dir aware that a drive is an
- autochanger (so the user doesn't need to use the Autochanger = yes
- directive).
-- Make catalog respect ACL.
-- Add recycle count to Media record.
-- Add initial write date to Media record.
-- Fix store_yesno to be store_bitmask.

-- Make hardlink code at line 240 of find_one.c use binary search.

-- Implement VolumeState as discussed with Arno.
-- Add LocationId to update volume
-- Add LocationLog
- LogId
- Date
- User text
- MediaId
- LocationId
- NewState???
-- Add Comment to Media record
-- Fix auth compatibility with 1.38
-- Update dbcheck to include Log table
-- Update llist to include new fields.
-- Make unmount unload autochanger. Make mount load slot.
-- Fix bscan to report the JobType when restoring a job.
-- Fix wx-console scanning problem with commas in names.
-- Add manpages to the list of directories for make install. Notify
- Scott
-- Add bconsole option to use stdin/out instead of conio.
-- Fix ClientRunBefore/AfterJob compatibility.
-- Ensure that connection to daemon failure always indicates what
- daemon it was trying to connect to.
-- Freespace on DVD requested over and over even with no intervening
- writes.
-- .update volume [enabled|disabled|*see below]

-- Restricted consoles start in the Default catalog even if it
- is not permitted.
-- When reading through parts on the DVD, the DVD is mounted and
- unmounted for each part.
-- Make sure that the restore options don't permit "seeing" other
- Client's job data.
-- Restore of a raw drive should not try to check the volume size.
-- Lock tape drive door when open()
-- Make release unload any autochanger.
-- Arno's reservation deadlock.
-- Eric's SD patch
-- Make sure the new level=Full syntax is used in all
- example conf files (especially in the manual).
-- Fix prog copyright (SD) all other files.
-- Document need for UTF-8 format
-- Try turning on disk seek code.
-- Some users claim that they must do two prune commands to get a
- Volume marked as purged.
-- Document fact that CatalogACL now needed for Tray monitor (fixed).
-- If you have two Catalogs, it will take the first one.
-- Migration Volume span bug
-- Rescue release
-- Bug reports
+- Why the heck doesn't bacula drop root priviledges before connecting to
+ the DB?
+- Look at using posix_fadvise(2) for backups -- see bug #751.
