Hi foggy,

thanks for linking my initial posting to this thread. Somehow I couldn't find a suitable topic, but this thread has it all. I'm really scratching my chin after reading this thread (and several linked ones). Chaining is - mostly - the devil.

Btw, why are you trying to run only a single job at a time?

Mostly out of fear that lets say 10 starting backup jobs will immediately create 10 snapshots that will exist longer than in a serial approach in total, maybe filling up the VM dastastore.
Follow-up question: When is a snapshot actually created? At around the job start, or when the ressource manager releases ressources to a backup job, allowing it to "actually" start?

A typical recommendation is to start all the jobs simultaneously (or with a short intervals) and limit the maximum number of proxy/repository concurrent tasks, if the resources load is your concern. This will allow you to reduce the backup time even more.

Indeed. I'll have to check this out. Starting jobs on Saturday will honor the Saturday AF flag for this job, even if it is delayed into Sunday because of ressource availability?

Thanks so far.

Snapshot is not triggered until actual resources are assigned to the task.

[MERGED] Job scheduling

Veeam Logoby Koni » Fri Apr 21, 2017 8:42 am

Hello,
I have problems to schedule a backup job. I would like to make an incremental backup of a vm from monday - friday. This is to start at 18 o'clock. Saturday I want to make of this vm an active full backup, but should start at 9 o'clock. How do I get the different times in the backup job?
In the backup job I have only the possibility to specify for the full backup days or months.
Is there a possibility or where is my mental error?

thanks,

carsten

Hello Karsten and welcome to the community!
Unfortunately, there is no such an option. Could you describe your use case?
Thanks!

hello,
thanks for your fast replay.
so, i will backup a vm. on monday - friday, i can start the backup only after 6 o clock in the afternoon. this is incremental. on sataurday, i will start a full backup from this vm. this full backup can start on saturday at 9 o clock in the morning.
I have the whole saturday time
my problems are, in the backup job, i can only schedule the full backup on days or month but no time ?!?!?
Or is my strategy wrong. Is it sufficient to make a full backup once and then only incremantal?

thanks, carsten

You may do increments only if you perform recovery verification.
But If you want to perform active fulls periodically, the best option is to schedule it on Saturday so it has both Sat and Sun to finish.
