Hello
We created maintenance plans for Backup, we configured as:
1. Backup set expires after 2 days. (but we still see backup files are at the location from day one)
2. There is Overwrite and Append in backup file settings. what eaxactly overwrites means, in case we set up expire the backup set after 2 days.
please advice. Thanks, Jay
If you are using a single backup device (whether it's a tape, file location...it's the same thing), overwrite means it will replace the backup on that device with the current backup. So that device will just hold the one backup. Append means it will add the current backup to the device. That device will hold multiple backups.
If you use a single device, set it to overwrite and the backup has not expired and you have selected the option to check the expiration date of the backup, you will get an error. It is designed to prevent you from accidentally overwritting a backup that you want to keep.
