Which is something *else* I do (for, say, NTBACUP or Windows Server
Backup), again by using that NFS or Samba share on my BackupPC server! :)
Basically, I often use my BackupPC systems as a combination NAS/Backup
server. Again, works very well.
If you're dealing with a bunch of SCSI (Really? Not SAS?) servers, I
assume you have *some* budget. I just spent less than $6,000 for a server
with 12 3TB SATA hot swap hard drives (rated for 24/7 operation, not
desktop drives), 2 x Intel Xeon E5 2.4GHz quad-core processors, 16GB RAM,
an LSI RAID controller and 4 x GbE and 2 x 10GbE. Configured for RAID-6
with hot-spare, I still got >24TB of space. That puppy moves >800MB/s to
the drives... All for $6k. If I had cut some corners on RAM and CPU (and
skipped the extra GbE ports) it would have been a little over under $4k.
That's enough space for more than 100 copies of a 200GB database.... And
you could still use BackupPC for keeping older copies around over time,
even if you don't get much help with pooling...
