just by changing to rsync. ;)
Solaris/debian/red hat boxes, all used to run the BrightStor client from CA, backing up to a tape library. The maintenance cost on the library was 5k, and the maint cost of the software was 5k.
You don't HAVE to pay the maint cost, but then there is no software upgrade path without paying full price, and no patches, no updates.
So we threw four 160gb drives in an old Optiplex box and used RH9 to raid two striped and raid two mirrored, so we keep everyone's home folders on the mirrored volume and the server backups on the striped volume. Then every night we rsync all of it from that server across a 1gb net connection to a near-dupe offsite, where I have it configured to keep three weekly archives of the server backups and a more complex backup for the homes folders.
every 4 hrs = 6/day
every day for 30 days
every month for 12 months.
Right now on the server we have 10 months of backups.
We use the copy method that creates a link, so we don't use the actual space required, we just link to the file that is in another folder. If you delete the main file, the closest link takes over as the main file - the space is allocated already, it just becomes primary. hard to describe, but it works.
Basically, it keeps each version of every file once, and all the other copies are just links. Works nicely! |
