Backup Strategies - how long should data be available?

I have a backup scheme with monthly, weekly and daily rotations. if a file is caught by monthly backup, it will be available for 4 months for restore. However, if someone creates a file on a tues and deletes the file on a wed in the middle of the month, it will probably only be available for the overwrite period of the daily incremental backup--10 days. That doesn't seem long enough.

I don't want to have an overwrite period of months for daily backups. How do others solve this issue of short-term files becoming unavailable to restore too quickly?

I have multiple weeks of daily and weekly backup tapes that i rotate (week1 - week5). I then also have a monthly tape and a quarterly tape. This will allow anything created and deleted before a weekly to be kept for 5 weeks.

Thanks.
How many rotations of daily tapes do you have? I have no rotation of dailies. I have 4 rotations of weekly and 4 rotations of monthly. The flaw in my plan seems to be the lack  of a daily rotation. But, to go for 4 months, I'd seemingly have to have a lot of daily rotations.

1) In BE you can create a Backup to disk to tape, which would backup to Disk and then duplicates to tape. You can keep the disk backup for a while and let the tape overwrite.

how to create B2D2T ? check out this links
------------------------------------
You will need to create a new policy with two templates, one for backup to disk and another to duplicate that to tape ...you can find ways to do it while searching in Google or BE admin guide..

Yep you would need 20 tapes just for daily rotation. If this is not fesable for you then you could look into B2D as an option.
