How to create a Tape-based Backup from a complete disk every Week?

[_Bugs_]

Hello,

i created a Backup Job to backup two volumes from a server to Tape. These Volumes should be backuped entirely every week at Saturday, 8 pm and the tapes should be overwritten after five weeks.

But the amount of data in the second week is much smaller than it was in the first week so i think that there will be only changed files backuped.

How do i set the jobs to backup the volumes entirely each Time?

Create a weekly full job with correct overwrite and append protection.

The job is configured with overwrite after 5 weeks and without append (1 hour).

Then you can check when exacly the tape under overwrite protected until, if this is past the date and time you want it to be overwriten you should consider to shorten the protection period.  Also the append period is a bit short if something happens, you want be able to resume if the problem is not fixed within 1 hour.

Sorry, i don`t understand what you mean.

I don`t want to append data to the tapes, i want to overwrite the tape without questions after five weeks.

Set your Overwrite Protection Period to 4 weeks, and Append to 0.

If they're FULL backups and they fit onto 1 tape, leave it as such. Shouldn't be a problem if the second week's data is less.

To backup your volumes in full and not just the changed files, change the backup method to full backup for all your jobs and not incremental or differential method.

I can`t set append to 0, it switches automatically to 1. I just can set the unit (hour, day,...).

They should be full backups on each tape, why is that not a problem when the second tape has less data?

The Backup Method is Full Backup, no incremental or differential here.

Solution: I had to include the shadow copy components as they contain the deduplication storage.
