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?
