We have an Amanda 3.1.3 running on Fedora 13. The Amanda server is backing itself and 2 other Linux servers to virtual tapes. Our data retention policy requires us to keep 90 days worth of backup. I anticipate we will run out of space on the HDDs currently allocated to Amanda backups in a week at the most. At that point, we would need to move some of the vtapes to external USB HDDs.

I was thinking what would be the best approach to accomplish this while still maintaining integrity of the backups - amvault, just copying the vtapes?

Your feedback would be greatly appreciated!
