Differential Jobs retentions
Can you please help with the below:
We have a tape drive (1 tape ,1 drive , tape size 400GB/800GB)... We want to take the file server with a differential backups daily from Monday till Friday. The File server size is 650GB, lets say we will need 1 full tape the first time we will run the differential backup because the Backup exec will take a full copy first time, the second day we will insert a new tape to run the differential job...
Question1: Since it is a new tape, Backup exec will be able to take only the difference from the last day or it will take it again as a full, because the last backup is on another tape?
If we are testing this scenario on a B2F it will take a full backup every time we change the B2F, is it the same for tapes?
Question2: If we want to restore from a differential backup in our case we will need 2 tapes (the differential backup and the full backup) is it duable if we have a tape drive (1 tape, 1 drive)?
Can we load the 2 tapes in this scenarion? or can we copy the content from tape to disk then do the restore?
Thank you in advance.
