[Bacula-users] Questions about spooling
Hi, I am doing some tests about spooling. I have created a spool filesystem for testing purposes. I decided to try a quiet small one - just 10 GB. Well, I get an ugly perfomance (10MB/s) with this one. So I assume that the spool file system is too small - is this assumption right? To get a bigger spool fs, there might be some options: 1) What is better: bigger spool fs or faster spool fs? So first option: 3,6 TB RAID0 with 12 SAS disks direct attatched vs second option: 2 or 3 120 GB SSDs? 2) Does it make any sense to have a spool fs much bigger than the tape size? (LTO4 - 800MB, with compression up to 1,6 TB - so does it make sense to use a fs 1,6 TB?) 3) Specially with the SSDs - will I run in problems because of MTBF? Is anybody using SSDs for spool fs? I have an autoloader with an SAS-LTO4 drive and I would like to get the drive to steam as fast as possible. Thanks for you answers!

[Bacula-users] Questions about spooling
Thanks fpr replying. @Alexandre: Yes, exactly, the 10MB/s (average) come from bacula job report. @Marcello: No - very time the spool fs is full (or the maximum spool size per job etc.) is reached the spool fs is despooled to tape. And that is where I hope to get the advantage from: despooling with full speed to tape. You are right, the fs has to be fast enough - which SSDs would be obviously. That the reason for the idea about them. A RAID0 with 12 disks direct attached with SAS should also be fast enough - but which option is the one to choose?

[Bacula-users] Bacula Catalog Backup to tape
Hi, I do my catalog backups to tape. I have an autoloader (Dell TL2000) with an LTO4 drive. I have created a pool Catalog containing two tapes. Since my catalog is not that big 8) all the catalog backups have been writen to the first tape in the pool. But I would like to switch the tape for every catalog backup - so first backup goes to first tape, second to second tape, third to first tape again, and so on. How is this posible with bacula?
