If we have a scenario like following, we have 10 server with 50 GB data each and want to do a disk backup and save data fore a possible restore 30 days (one backup every night).
We have 2000 GB disk area to save the backups.
We have the same media set for all servers.
The settings on the backup jobs (several different backup jobs but using the same media set) are "when this job begins" "append to media. Overwrite if no append able media is available"
At the media set periods we have are: overwriting protection period 12 weeks, append period infinitive allow append.
Now what happen with the disk area at 2000 GB!
First the backup jobs is using free disk space the first 12 week, then when the overwriting protection period is past is the backup then first use free disk space or it is overwriting the old backup "files"?
