I use SQLsafe to backup and compress my data, which in turn is saved to
my backup server. My tape is HP's Surestore 6/6000 library. I have
5540GB tapes in the library.
Monday through Saturday I perform a differential backup and a full
backup on Sunday. My plan is to keep a 1 month worth of data on the
shared disk (890GB currently, upgrading to 10 300GB raid5 next year).
Once the full backup is a month old, I move it to the library and
delete the files from the disk once the backup is successful. I wont
backup the diffs to tape and will delete the prior weeks diff backups
once the full backup is complete.
This is my current plan, it will change as I get useful input and see
how it works in practice.
My full backup of some tables are not currently large; the largest
5.3GB after compression. However, I tend to look forward, and forsee
more demand on the backup server, so why backup data that hasnt
changed? The library will be backing up 3 Linux servers, 16 windows
servers, 5 SQL and 3 Sun machines with more to come. So, I wish to
maximize the storage on the Library by keeping unnecessary data off the
library.
Again, there may not be a practical solution to my question, but often
I find I learn something unrelated that may help me with a future
problem.
