How to do incremental and full backup in 2 jobs

Post by speedfan » Aug 26, 2019 9:10 am

Hello everyone,

I think this is a topic who is often create but I didn't find anyone who fit with my problem.

We're using veeam backup, and I wanting to do this :

1 - Incremental backup monday, Tuesday, wednesday, thursday, friday
2 - Full backup saturday and sunday

I need to do this in 2 differents jobs (I think) because the full backup are very longer than incremental.

IT's very simple, but I don't find who to do this with veeam.

Do I have to do 2 differents jobs ? If so, how to configure it ?

Thanks all.
Regards

Hi Greg and welcome to the Veeam community!

You can do it by using the Forward incremental backup method with only one backup job.
Please review the article in the user guide about Backup chain for additional information.

Thanks!

Hi,

So if I understand well, with this option "synthetic full backup", he's doing one full backup at first, daily there is an incremental, and, sunday, for example, all the incremental are merge with the first full backup ?

But I want to do this :

Job 1 : incremental monday, Tuesday, wednesday, thursday, friday at 21pm with 14 days retention
Job 2 : incremental monday, Tuesday, wednesday, thursday, friday 22pm with 14 days retention

Job 1 : Full saturday : 2pm with 14 days retention
Job 2 : Full saturday : 4pm with 14 days retention

I got more than 2 jobs but it's for the example.

Thanks

Hi Greg!

I'd suggest to review this animated article to see the difference between active and synthetic full methods (look under "Synthetic Full Backup" and "Active Full Backup").
The configuration mentioned above seems to be valid: each job can have its own schedule.

By the way, you can find more info about synthetic method here.

Thanks!

That's correct, the synthetic full is created by merging data contained in the repository.

Every backup chain is starting from the full backup and cannot consist only of increments.

Thanks!

Thank for your answers.

With "Synthetic Full Backup", like we said, there is a full --> Daily incremential --> Merge daily incremental Saturday (for example) --> Daily incremental --> Merge ...

With this solution, we have only one full backup.
If we're the 20/08, on monday, with a full backup from saturday, and I want to restore the machine from the 10/08, I can't, correct ?

So it's a problem because if we've a problem on the server who occur the 12/08, we can't restore it from the 10/08.

With "Active Full Backup" it's ok for me, but we cannont set a different schedule (time).
We've to use the same time and it's a problem because full backup are much longer than incremental.

And what do you think about possible increase of restore points?

I propose to look at this example and to keep in mind that retention logic works in the same way in both cases, the only difference is the method of .vbk file creation:
synthetic is created using backup files that are already available in the backup chain, full is created by retrieving data for the whole VM from the source.

Thanks!

Hello,

Sorry but I'm a bit confuse.

It's new for me, and I want to clarify thing :

- If I use "Synthetic Full Backup" with a 14 days retentions, it will be ok if we're the 20/08, on monday, with a full backup from saturday, and I want to restore the machine from the 10/08 ?
Because with this one, it merge the daily to recreate a full, so the previous full is erase, correct ?

- If I use "Active Full Backup" (on saturday) with a 14 days retentions, it will be ok if we're the 20/08, on monday, with a full backup from saturday, and I want to restore the machine from the 10/08 ?
If I understand well, this method create a full, then daily, and create an other full on saturday. With the 14 days retentions, there will be 2 full backup and daily backup, right ?

Thanks

Hi,

Starting on 10th of August with the retention set to 14 you will get 2 fulls + 9 increments by August 20.
You can restore a machine from 10 to 20 August no matter how the fulls are created.

Thanks!

My example is related to the Forward Incremental Backup method. Thanks!

Retention setting specifies the number of restore points to keep on disk, so whatever method you select, you will not have less number of restore points that you've specified. There will be just a difference in the total number of fulls/incrementals in the particular chain. If the point you need to restore at is covered by retention, you will be able to restore.
