I am looking for another backup solution for our situation here. Let me explain the scenario:
We are backing up 20 servers total at five different sites which amounts to about 1TB of data total. At three of the sites, we have Dell PowerVault tape drives (1SDLT and 2LTO drives). Site 1 and 2 backup to LTO#1, sites 3 and 4 backup to LTO#2 and site 5 backs up to its own SDLT. We are using Symantec BackupExec 11d and take the monthly backup tapes off site each month.
The issue is that the backups take way too long (for a full backup) and we have to end up changing out the tapes frequently to ensure that we get a good backup which can be a real hassle.
I was considering maybe going to a hard drive backup, possibly some external drives.
My question is, what would you recommend in this case (hardware wise) and what software would you do it with?
