What is the retention period I need to set for my Yearly backup to Tape. (Media set propeties please see the screenshot attached).
Retention perid/ overwrite protection period / Append period.
Please note this a one time backup only. Backup to Tape drive (LTO6)
The purpose of this backup is to keep every year a copy of that year's backup in a seperate LTO Tape. (This is not going to overwrite). This is only for future use in case management needed any files from previous years.
I need a proper retention policy to keep for these kind of backups. Thank you.
