Hi!

I would like to perform the following backup task:

Monday: Full Backup (25GB)
Tuesday: Incremental (5GB)
Wedensday: Incremental (5GB)
Thursday: Incremental (5GB)
Friday: Incremental (5GB)

Could somebody give me an advice regarding a backupstrategy, the following points included:
- Tape retention time.
- Use each tape once?
- How many tapes should be used (5?)
