Re: [Bacula-users] label command frequently fails

I recommend trying your label command again, but turn on debug with something link setdebug level=150 Storage prior to doing the label command. It should give you a more detailed reason for the failure. It gives me the exact same output. It took the setdebug command but continues to complain when I try to label a new volume. After a reboot I was able to label a volume however. After a while I lose that ability once more. Meanwhile I am currently getting messages every minute to the effect: 25-Sep 23:36 bacula-dir JobId 3284: Pruning oldest volume "weekly-backup-pool-03" 25-Sep 23:36 bacula-dir JobId 3284: Found no Job associated with the Volume "weekly-backup-pool-03" to prune (repeated at 23:37, 23:38, etc.) This is possibly unrelated but I don't think it should be happening either. ___ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
Re: [Bacula-users] deleting specific folders from backups

AFAIK there is no way to modify Bacula backups after they have been created. The only way to remove a file from all backups is to erase all the volumes it may have ended on, thereby destroying all the backups which contained it, and an indefinite number of other backups along with it. ___ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
[Bacula-users] deleting specific folders from backups

I know how to filter things a little bit with sed + regex but I am not sure for example how to sort by full path name preserving all the other columns displayed by `estimate listing`.

Re: [Bacula-users] CFLAGS optimizations and building for another architecture
Hi Josh, You seem to be replying to an earlier message (about CFLAGS optimizations) quoting the latest one (which is about building for another architecture), so at first that got me confused. FWIW: I don't use software compression (the storage has hardware compression). -- George ___ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users

Sorting inside Bacula would consume resources which is not what you want. External sorting require some additional scripting which you can do in a few minutes then you can add some filtering if you wish. You can even load all estimation data to database and do sorting, filtering, aggregation, etc. Possibilities are endless and limited by your imagination. Developing this kind of functionality inside Bacula require a lot of effort and time. If you want to contribute a such functionality, you are welcome. best regards -- Radosław Korzeniewski rados...@korzeniewski.net ___ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users

Do I need anything more than just finding the proper "-march" setting for the target CPU? I'm not sure you need to do even that. The default should be to produce code that will run on all supported CPUs (of the same instruction set architecture). Unless you need to cross-compile, or to target a CPU so old that it is no longer supported by default (e.g., a 80x86 with x<6), you probably don't need to do anything special. Creating a 32-bit build on a 64-bit system may require you to use -m32 (or whatever the exact syntax is) or (my preferred approach) to build in a 32-bit environment (chroot, container or virtual machine). I am particularly interested in building FDs for two types of CPUs. I am attaching the /proc/cpuinfo for both. Could you advise on specifics? I'm not sure whether compiler optimizations will make a huge difference. The FD is quite i/o bound, in general. However, there are exceptions. On clients with weak CPUs, enabling compression and/or encryption will very much affect performance. If software compression is required, then try to use LZO. Weak clients will usually perform better with compression disabled, in spite of the increased network traffic. ___ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
