Ditto for files with - extra/fewer hard links than at the time of the last Full backup. - - Why: Incremental/Differential would be much more useful if this worked. - - Notes: Merging of multiple backups into a single one seems to - rely on this working, otherwise the merged backups will not be - truly equivalent to a Full backup. - - Kern: notes shortened. This can be done without the need for - inodes. It is essentially the same as the current Verify job, - but one additional database record must be written, which does - not need any database change. - - Kern: see if we can correct restoration of directories if - replace=ifnewer is set. Currently, if the directory does not - exist, a "dummy" directory is created, then when all the files - are updated, the dummy directory is newer so the real values - are not updated. - -Item 2: Implement a Bacula GUI/management tool. - Origin: Kern - Date: 28 October 2005 - Status: - - What: Implement a Bacula console, and management tools - probably using Qt3 and C++. - - Why: Don't we already have a wxWidgets GUI? Yes, but - it is written in C++ and changes to the user interface - must be hand tailored using C++ code. By developing - the user interface using Qt designer, the interface - can be very easily updated and most of the new Python - code will be automatically created. The user interface - changes become very simple, and only the new features - must be implement. In addition, the code will be in - Python, which will give many more users easy (or easier) - access to making additions or modifications. - - Notes: There is a partial Python-GTK implementation - Lucas Di Pentima but - it is no longer being developed. - - -Item 3: Implement Base jobs. - Date: 28 October 2005 - Origin: Kern - Status: +* => item complete + +Item 1: Ability to restart failed jobs +Item 2: SD redesign +Item 3: NDMP backup/restore +Item 4: SAP backup/restore +Item 5: Oracle backup/restore +Item 6: Zimbra and Zarafa backup/restore +Item 7: Include timestamp of job launch in "stat clients" output +Item 8: Include all conf files in specified directory +Item 9: Reduction of communications bandwidth for a backup +Item 10: Concurrent spooling and despooling within a single job. +Item 11: Start spooling even when waiting on tape +Item 12: Add ability to Verify any specified Job. +Item 13: Data encryption on storage daemon +Item 14: Possibilty to schedule Jobs on last Friday of the month +Item 15: Scheduling syntax that permits more flexibility and options +Item 16: Ability to defer Batch Insert to a later time +Item 17: Add MaxVolumeSize/MaxVolumeBytes to Storage resource +Item 18: Message mailing based on backup types +Item 19: Handle Windows Encrypted Files using Win raw encryption +Item 20: Job migration between different SDs +Item 19.

Must completed have a minimum + volume of data or files stored on Volume before enabling. + +Item 2: SD redesign + Date: 8 August 2010 + Origin: Kern + Status: + + What: Various ideas for redesigns planned for the SD: + 1. One thread per drive + 2. Design a class structure for all objects in the SD. + 3. Make Device into C++ classes for each device type + 4. Make Device have a proxy (front end intercept class) that will permit control over locking and changing the real device pointer. It can also permit delaying opening, so that we can adapt to having another program that tells us the Archive device name. + 5. Allow plugins to create new on the fly devices + 6. Separate SD volume manager + 7. Volume manager tells Bacula what drive or device to use for a given volume - What: A base job is sort of like a Full save except that you - will want the FileSet to contain only files that are - unlikely to change in the future (i.e. a snapshot of - most of your system after installing it). After the - base job has been run, when you are doing a Full save, - you specify one or more Base jobs to be used. All - files that have been backed up in the Base job/jobs but - not modified will then be excluded from the backup. - During a restore, the Base jobs will be automatically - pulled in where necessary. - - Why: This is something none of the competition does, as far as - we know (except perhaps BackupPC, which is a Perl program that - saves to disk only). It is big win for the user, it - makes Bacula stand out as offering a unique - optimization that immediately saves time and money. - Basically, imagine that you have 100 nearly identical - Windows or Linux machine containing the OS and user - files. Now for the OS part, a Base job will be backed - up once, and rather than making 100 copies of the OS, - there will be only one. If one or more of the systems - have some files updated, no problem, they will be - automatically restored. - - Notes: Huge savings in tape usage even for a single machine. - Will require more resources because the DIR must send - FD a list of files/attribs, and the FD must search the - list and compare it for each file to be saved. - -Item 4: Implement from-client and to-client on restore command line. - Date: 11 December 2006 - Origin: Discussion on Bacula-users entitled 'Scripted restores to - different clients', December 2006 - Status: New feature request - - What: While using bconsole interactively, you can specify the client - that a backup job is to be restored for, and then you can - specify later a different client to send the restored files - back to. However, using the 'restore' command with all options - on the command line, this cannot be done, due to the ambiguous - 'client' parameter. Additionally, this parameter means different - things depending on if it's specified on the command line or - afterwards, in the Modify Job screens. - - Why: This feature would enable restore jobs to be more completely - automated, for example by a web or GUI front-end. - - Notes: client can also be implied by specifying the jobid on the command - line - -Item 5: Implement creation and maintenance of copy pools - Date: 27 November 2005 - Origin: David Boyes (dboyes at sinenomine dot net) - Status: - - What: I would like Bacula to have the capability to write copies - of backed-up data on multiple physical volumes selected - from different pools without transferring the data - multiple times, and to accept any of the copy volumes - as valid for restore. - - Why: In many cases, businesses are required to keep offsite - copies of backup volumes, or just wish for simple - protection against a human operator dropping a storage - volume and damaging it. The ability to generate multiple - volumes in the course of a single backup job allows - customers to simple check out one copy and send it - offsite, marking it as out of changer or otherwise - unavailable. Currently, the library and magazine - management capability in Bacula does not make this process - simple. - - Restores would use the copy of the data on the first - available volume, in order of copy pool chain definition. - - This is also a major scalability issue -- as the number of - clients increases beyond several thousand, and the volume - of data increases, transferring the data multiple times to - produce additional copies of the backups will become - physically impossible due to transfer speed - issues. Generating multiple copies at server side will - become the only practical option. - - How: I suspect that this will require adding a multiplexing - SD that appears to be a SD to a specific FD, but 1-n FDs - to the specific back end SDs managing the primary and copy - pools. Storage pools will also need to acquire parameters - to define the pools to be used for copies. - - Notes: I would commit some of my developers' time if we can agree - on the design and behavior. - -Item 6: Merge multiple backups (Synthetic Backup or Consolidation). - Origin: Marc Cousin and Eric Bollengier - Date: 15 November 2005 - Status: Waiting implementation. Depends on first implementing - project Item 2 (Migration) which is now done. - - What: A merged backup is a backup made without connecting to the Client. - It would be a Merge of existing backups into a single backup. - In effect, it is like a restore but to the backup medium. - - For instance, say that last Sunday we made a full backup. Then - all week long, we created incremental backups, in order to do - them fast. Now comes Sunday again, and we need another full. - The merged backup makes it possible to do instead an incremental - backup (during the night for instance), and then create a merged - backup during the day, by using the full and incrementals from - the week. The merged backup will be exactly like a full made - Sunday night on the tape, but the production interruption on the - Client will be minimal, as the Client will only have to send - incrementals. - - In fact, if it's done correctly, you could merge all the - Incrementals into single Incremental, or all the Incrementals - and the last Differential into a new Differential, or the Full, - last differential and all the Incrementals into a new Full - backup. And there is no need to involve the Client. - - Why: The benefit is that : - - the Client just does an incremental ; - - the merged backup on tape is just as a single full backup, - and can be restored very fast. - - This is also a way of reducing the backup data since the old - data can then be pruned (or not) from the catalog, possibly - allowing older volumes to be recycled - -Item 8: Deletion of Disk-Based Bacula Volumes - Date: Nov 25, 2005 - Origin: Ross Boylan (edited - by Kern) - Status: - - What: Provide a way for Bacula to automatically remove Volumes - from the filesystem, or optionally to truncate them. - Obviously, the Volume must be pruned prior removal. - - Why: This would allow users more control over their Volumes and - prevent disk based volumes from consuming too much space. - - Notes: The following two directives might do the trick: - - Volume Data Retention =
