Veeam Backup

I have scheduled to backup our server from Mon - Fri at 8:30PM. However, I find that the job will carry out a full backup on server on Sat. Any idea ? I'm using Veeam Backup & replication 7.0

Thx

At the bottom you have Active Full, de-select this setting. Or Synthetic full is selected under Incremental.

Hi,
agree with DirkMare, it should be synthetic or active full configured at the step he shows.
Seeing the transferred data size (around 3 GB) it should be the synthetic full backup which must be enable. For the synthetic full Veeam run an incremental on the production servers, then build a full backup file with this incremental and the last past ones since the last full.

By default, does it click or not ?

I have another VMware that doesn't click this option. Is it important to ensure Active full backup should be elected ? Do I have rescovery issue if this option do not click ?

Thx again.

Our veeam server have these setup as its defaults. This was not changed in anyway from day of installation.

For Incremenetal [recommended] without selecting "Create synthentic full backups peridically", which "full backup copy" does it relie on for disaster recovery ?

Thx again.
Dirk MareSystems Engineer (Acting IT Manager)Commented:
Not just the Full but all of the backups.

Sorry, I can't exact your idea. Can you explain further ? Thx again.
Dirk MareSystems Engineer (Acting IT Manager)Commented:
Let's say you create a backup daily and the first backup (FULL) happens on Monday and you want to restore your System on Friday. You will need all the backups, Mon to Thurs.

For instance if you create daily backups and you want to restore a backup two months later you would probably need all the backups from the very first backup.

The examples are only if you make a Full System Restore.

My recommendation would be to make a active full every now and then.

Mr TorturSystem EngineerCommented:
Hi,
I would advise you to make full backup, at least synthetic full once per week.

As Dirk Mare told you, if you stay with the default Veeam parameters, you will be in an incremental forever way, without full backup.
That mean you will have a first full, and then incremental, forever.
(And your backup files will never be purged, but well, that's another subject.)
That mean for a restore you will need the first full and all the other incremental backup files, could be hundred of files if you restore something one year after the installation.
If one of the files is corrupt, even the smalest, all your restore won't work.

Best configuration example IMHO :
"incremental (recomended)" from monday to friday or saturday
synthetic full backup friday or saturday
Active full once per month on sunday

But you have to take into account the number or restore points you want to keep, your available disk space, your company working hours, etc...

Is it fine for my new setting ? Thx

BTW, for "Reversed incremental", does it mean each incremental backup is enough to fully recovery my server, as stated in the description (Each increemntal run produces full recovery file of the most recent state) ?

Thx

Correct but it will use more space see example below.

Backup of server using reverse incremental.
1st backup is FULL
2nd all changes from full
3rd all changes from full
4th all changes from full
Reverse incremental does not change the archive option meaning every backup after full will have every backup in between (effectively backing-up data that was already backed up previously). The only "con" is it uses more backup space the "pros" restoring of backup is quick less files.

What is your retention policy set to?

30.

Currently, there are 13 backup job schedule to run on the server. First one will be start at 8:30PM and the other will be shedule to follow the previous one after completion using the option "After this job" setting.

So, for full backup on each server, I also need to specify the "Active full backup" setting on each job, correct ? Will it casuse contention on servers for all Full backup job to start, say on Friday as there is not time or prioirty for further control.

Thx
Dirk MareSystems Engineer (Acting IT Manager)Commented:
Correct, you will have to set it on each backup. It depends on the size of the backup are these large servers?

How long does it take for each server to complete a full backup?
