I backup to disk then copy to LTO4 tape. All the servers in question are on a 10Gb network.
The bacula-sd on disk has a 10x 5TB raidz3 ZFS array. I am not sure of my read speeds there, but I know there is no room to attach the LTO4 tape library on that server. I have two spare servers which can be attached to the library: * Dell R610 - cheaper to run - only SSDs in here. * Dell R710 - about 2.6 times more expensive to run, no SSD. When I copy to tape, I usually run multiple jobs at once. There are are two bigger jobs, and one or the other usually streams alone for a while. Here are the scenarios I have mulling over in my head: * use the R610, add a 128G SATA SSD drive for spooling. That will saturate the drive. * use the R610, don't spool since it's a 10Gb network. This is contingent upon getting at least 120MB/s from the first bacula-sd. * use the R710: it has about 5TB of disk space; I could copy to there, then spool to disk; then more copies of the backup exist. Also contingent upon getting at least 120MB/s from the first bacula-sd. Do you have other ideas / suggestions / things to consider? Recommendations?
