Re: [Bacula-users] LTO3 tape capacity (variable?)
Zitat von Stephen Thompson step...@seismo.berkeley.edu: Thanks for the info, John. Is there anyone else in the bacula community with LTO3's seeing this behaviour? I don't believe (but am not 100% sure) that I'm having any hardware-related issues. Not sure what to make of this. About 25% of tapes in a monthly run (70 tapes) are under the 400Gb native, but then the other 75% are above it, some even hitting the 800Gb top. As said by others. The native capacity is 400Gb and Bacula simply writes to the tape until the write does not succed which Bacula take as tape full. If you have some (full) tapes with less than 400Gb you either have some older tapes (LTO-2) or problem with your hardware or tapes. The tapes with more than 400Gb simply contains data which can be better compressed by the built-in compression of the drive.

I don't think this explains your issue, but LTO drives will write the data to the tape, and then immediately read it again (the read head is placed such that this is possible). If the read is bad the drive will rewrite the data. This ensures that you get a good write, but obviously decreases the effective capacity of your tape. Your tapes would have to be pretty worn out to drop the capacity to 25% though.

[Bacula-users] Disaster Recovery Test
Now that I have been running Bacula for several months, I was working on testing disaster recovery, just in case I need to. I am a little lost though on what I need to do to get the database restored. I am going on the assumption that All I will have is the off site data (hopefully not ever this bad as this is my home system). I have a nightly admin job that kicks off a Python script on the server which creates a bzipped tar of my Bootstrap files, state files, and the server/client configuration files and emails that to my gmail account. So for my test I built a virtual machine (Original and test system running FreeBSD 9.0-RELEASE-p4), installed PostgreSQL, and Bacula, created the initial Bacula tables, restored the configuration, bootstrap, and state files from my emailed tar file. Here's where things go a little wrong, I mount my external backup drive to the test server, launch bconsole, and issue the status command for the client, since I restored the state files, I can see the job ID of my last catalog Backup. Then issue the run command, select restore, enter the job ID when prompted, and select mod, enter the bootstrap file from the catalog backup and start the job. It returns pretty quick with Media record not found, so I am guessing I am missing a step that would load the volumes on my external backup drive to my new system before it can restore the catalog, from that volume, or am I missing something else?

Re: [Bacula-users] LTO3 tape capacity (variable?)
Thanks everyone for the suggestions, they at least give me somewhere to look, as I was running low on ideas. More info... The tape in question have only been used once or twice. The library is a StorageTek whose SLConsole reports no media (or drive) errors, though I will look into those linux-based tools. Our Sun/Oracle service engineer claims that our drives do not require cleaning tapes. Does that sound legit? Our throughput is pretty reasonable for our hardware -- we do use disk staging and get something like 60Mb/s to tape. Lastly, the tapes that get 200 vs 800 are from the same batch of tapes, same number of uses, and used by the same pair of SL500 drives.

I am a little lost though on what I need to do to get the database restored. I am going on the assumption that All I will have is the off site data (hopefully not ever this bad as this is my home system). I have a nightly admin job that kicks off a Python script on the server which creates a bzipped tar of my Bootstrap files, state files, and the server/client configuration files and emails that to my gmail account. So for my test I built a virtual machine (Original and test system running FreeBSD 9.0-RELEASE-p4), installed PostgreSQL, and Bacula, created the initial Bacula tables, restored the configuration, bootstrap, and state files from my emailed tar file. Here's where things go a little wrong, I mount my external backup drive to the test server, launch bconsole, and issue the status command for the client, since I restored the state files, I can see the job ID of my last catalog Backup. Then issue the run command, select restore, enter the job ID when prompted, and select mod, enter the bootstrap file from the catalog backup and start the job. Hello I have myself not fully tested disaster recovery but as far as i know you need a valid bootstrap from your catalog (database) backup. With this you can first recover the catalog backup (ASCII dump) and then use the tools provided for you database to import this dump. After that you are up and running to restore from your volumes. If you don't have a recent catalog backup you might use bscan to create needed records by scanning your volumes. Restore a bootstrap file is explained here: http://www.bacula.org/5.2.x-manuals/en/main/main/Restore_Command.html#SECTION002914 After reading this over again for the hundredth time give or take a few times, I finally figured it out, if you keep going through the console log, it did actually restore a file despite the fatal error messages local-dir 5.2.12 (12Sep12): Build OS: amd64-portbld-freebsd9.0 freebsd 9.0-RELEASE-p4 JobId: 1 Job:RestoreFiles.2012-09-24_20.43.59_07 Restore Client: bacula.dweimer.local-fd Start time: 24-Sep-2012 20:44:01 End time: 24-Sep-2012 20:44:25 Files Expected: 0 Files Restored: 1 Bytes Restored: 562,544,754 Rate: 23439.4 KB/s FD Errors: 1 FD termination status: OK SD termination status: Error Termination:*** Restore Error *** 24-Sep 20:44 bacula.dweimer.local-dir JobId 1: Begin pruning Jobs older than 20 days . 24-Sep 20:44 bacula.dweimer.local-dir JobId 1: No Jobs found to prune. 24-Sep 20:44 bacula.dweimer.local-dir JobId 1: Begin pruning Files. 24-Sep 20:44 bacula.dweimer.local-dir JobId 1: No Files found to prune. 24-Sep 20:44 bacula.dweimer.local-dir JobId 1: End auto prune. I was not actually paying attention and processing this part of the page: You will then need to follow the instructions for your database type to recreate the database from the ASCII backup file. See the Catalog MaintenanceCatMaintenanceChapter chapter of this manual for examples of the command needed to restore a database from an ASCII dump (they are shown in the Compacting Your XXX Database sections). However if the job didn't give me a fatal error I might have looked on more since this was after the restore job information, when I checked the /tmp/bacula-restore folder, sure enough under a few more folders was the SQL dump of the database. When I got to the fatal error in the restore console log, I just started back over at the top, thinking I missed something along the way, instead of looking farther to see if there was something after that part that still needed done, despite having the error message. -- Thanks, Dean E.

[Bacula-users] How to change Maximum Volume size in Pool definition?
Hello,
I'm new to bacula. I have a Pool that was set to 50GB in size. It's full now.
I'd like to increase it's size now.
I tried simply changing the 'Maximum Volume Bytes' attribute, and, in
succession, a reload, force-reload, and restart of the bacula-dir service, and
then also the bacula-sd service. However, the bat still reports the Pool as
the original size. How can I change it?
Here is the pool definition in it's entirety, in case that helps:
Pool {
Name = File
Pool Type = Backup
Recycle = yes # Bacula can automatically recycle Volumes
AutoPrune = yes # Prune expired volumes
Volume Retention = 365 days # one year
Maximum Volume Bytes = 50G # Limit Volume size to something
reasonable
Maximum Volumes = 100 # Limit number of Volumes in Pool
}
