Health check best practice for our case

Veeam Logoby FXE » Mon Mar 20, 2017 9:38 am

Hi all,

I want to optimize our backup policy following the upgrade to Veeam B&R 9.5 Update 1 and the installation of a new backup repository.

First question : space usage
Today we have a backup job that creates a full backup a week with 5 incremental backups.
The chain is like [FULL on sundays (~3TB) ; INC on mondays/tuesdays/wednesdays/thursdays/fridays (~350GB)]. The retention period is set to 14 points.
Currently, I have 3 complete chains and a new full created yesterday. So I have 4 full backups and 14 incremental backups (the first chain contains only 4 incremental backups) that take 15TB.
My new repository is near out of space and I think about reduce full backups ocurences like [FULL the first end third sundays (~3TB) ; INC on mondays/tuesdays/wednesdays/thursdays/fridays (~350GB)].
This new schema will allow us to have 2 complete chains that will use ~12TB (2 full backups and 20 incremental backups.
--> Will that a good way ?

Second question : Health check
Since our Veeam has been upgraded to 9.5 Update 1, we have set Health check.
Currently, It is launched after the first incremental backup following a full backup.
--> Should it be launched after each incremental backup ?

Thank you for your help.
Have a good week.

Hi,
The best practice is to use forever forward incremental job with periodic Surebackup verification.
This way you will have just one full backup and your backup will have a proven recoverability.
Thanks!

Hi and thank you for your answer.

OK, but how and where could I set this . In backup Advanced settings, I only have "Reverse incremental" and "Incremental (recommended)" options. Nothing about "forever forward incremental" or "SureBackup".

Backup job works as Forever Forward Incremental when you disable full backups.
Surebackup is a job for backups verification.
Please check hyperlinks for more info.

OK, but we don't want to implement SureBackup now.
So how should I deal with Health check ?

Thank you.

You may use Health Checks for Forever Forward Incremental as well. It`s up to you how frequently to start it. I would say you may not need it work more often than weekly.

If a health check takes more than 24hrs to complete, are incremental backups still run whilst its checking?

Usually it takes less than a day, but if you healthcheck is not finished it should be interrupted by backup job. Let me check it.

Actually the new job run will not happen if healthcheck is not finished. That`s because healthcheck is a part backup job, i.e. during healthcheck process the job is indicated as "running".

Would a health check take the same time as a job validator task? As when I run validator, some jobs take over 24hrs to complete, but the next backup runs, unless its a weekend where a transform happens.

That's all good to know, but do the 2 processes take a similar time to complete? I realise I can just test myself, but Im lazy and just want you to tell me :mrgreen:

Backup Validator should take longer, since it recalculates checksums for the entire backup chain, while health check verifies the latest restore point only.
