I have a backup server running System Center Data Protection Manager 2012, connected to a couple of tape drives (no library). I also have, of course, some tapes. Tape rotation is manual.
The tape have been used before, by DPM itself (but the server has been completely rebuilt) and by other backup softwares; they are not emtpy.
I'm contemplating an auto-loading tape drive as part of a backup strategy. This would be my first experience with tape backup. The cost-effectiveness of tape drives seems to depend on the assumption that they will provide many years of service. I'm having a difficult time assessing how many years of service to expect from a tape drive, however.
I've got some data that is being backed up to tape via bacula, and at some point soon I am going to need to migrate to non-tape storage.
Bacula supports to-disk archiving, but it occurred to me that if only there was some virtual tape library interface to S3 or openstack Swift, or some other object store service, I could just swap out the configurations and maintain the pre-existing archiving, ag
Linux supports SCSI, IDE and old floppy based tape devices. Each device has unique name just like hard disk drives.
I was switching the disk drives in my server, running RAID 6 on 5 disks on a 3ware 9650SE controller, for newer disks and have run into a problem.
The two first disks went fine, I took out one disk and inserted a new one, let the array rebuild and repeated for disk 2.

Brief question about partition layout. I use an SSD for /, /boot, /usr, & /home partitions. I'd like to move /var to a mechanical disk to minimize writes to the SSD.
Okay I have a question for all you techies out there. We know about hard disk cloning, and lately I've been reading about spanned volumes in Windows. So with spanned volumes, you can take 2 or more hard disks and span the partition across disks, allowing you to assign 1 drive letter to the disks, sort of like LVM in linux.
What things should I check to confirm that compression is actually happening on our tape backup system? Although the tapes are marked as 200G/520G (native/compressed) capacity, they seem to fill up before the 200G mark (some less than 100G).
i have a quantum scalar i40 connect on a centos 5 machine trough SAS interface.
I fight with it since a while because the media changer does not work.
