backup

[mikeh]

our office backs up once a week at a cost of $100/tape. It takes 11 tapes to do a complte backup. This translates to $1,100 a week for backup. It seems like there must be a cheaper way. Is there?

I make dual daily automatic backups to 500GB mini portable USB harddisks: this is not incremental, just synchronizing. In all programs I work with I save incremental (which are also sync'd to the USB disks) and after project end the incremental backups are deleted on all disks for 90 %. Next to that I have disk arrays at home and at the office which carry all projects/data from the last 2-3 years. When the USB disks are full I keep 1 at home and 1 in a safe. It takes between 3-6 months to fill up the disks, before I have to buy new ones.

whoa, what's your capacity?

Sounds like you are running AIT4 or LTO4

We run a 48TB system and do full backups quarterly with incremental in between. You should not need a full BU ever week. This way in your case you would be spending about 1400 a quarter as the incremental is not that much space.

quarterly is way to infrequent. We make changes to exhibits dailey, hourly, minute by minute. We are a Planning, civil eng, survey company with 3d when required.

Backups

We mirror our drives and backup to our TB backup device nightly.
