Backup strategy and tape rotation issue
Posted on 2007-03-27
I`m lookiing to revamp the backup solution for one of my clients. They have a tape drive which had a far higher capacity than what is being backed up.
The current solution is a full backup everyday and the tape rotation scehme is M,T,W,T,Fri1,Fri2,Fri3,Month1,Month2,Month3
I have identified a problem with this whereby thecycling of tapes means that a file deleted on tuesday would only be recoverable from the preceding monday tape. Once the next monday comes around this tape is overwritten and the file is non recoverable.
Can anyone suggest a better strategy to alleviate this?
