Backup to tape latest restore point

[flesz]

Hi All,

I was wondering why my backups to tape are not saving the latest restore point.
We are doing forever incremental backups to disk and keep 23 restore points.
I am scheduling monthly backup to tape and want to backup only latest full backup.
However if I schedule the job to run at the end of the month it is usually backing up the restore point which is 1 week old.

For example I ran a test backup to tape today for the group called DMZ which has latest restore point from today (01/12)

Here is the screen of the job



Here is the log after backup to tape completed

Code: Select all

As visible from the log it saved the DMZ from 26/11 rather than 01/12.
My question is why is it not saving the latest restore point to tape and instead it is choosing the one from 26/11 (DMZ2016-11-26T022232.vbk) ?

Hi Patrick,

I am scheduling monthly backup to tape and want to backup only latest full backup.

To clarify, are you using 'Backup only latest chain' option in tape job?

Hi Dmitry,

I have Process latest full backup chain option selected, I think that's the one you are asking about?

[Dima P.]

Can you check the synthesized full backup schedule as well? Go to backup to tape job properties > Full backup step and click the Schedule button, it should display scheduled dates

Hi Dimitry,

I think we might be on something here.
I have checked and it is configured to run on Saturdays only


Checking my original post DMZ job the log shows it was using the backup from 2016/11/26 which was Saturday.

So i presume if I select all days in there , my monthly backup to tape should use the latest restore point?

Hi Patrick,

This schedule defines the day when full backup should be from source backup chain. If there is a full – it will be placed to tape, if there is no full backup – synthesized full backup will be created and saved to tape. In this schedule pick the date when you want full backup from the source chain on disk, schedule tape job and check process latest full backup chain only option. In your case tape job schedule and full backup schedule should be one date.
