Copy Job Interval

[pcoady@syssrc.com]

If during the bckaup copy job interval, more than 1 source restore points is created, are they both copied? For example:
1) Source backup job creates a new restore point at the beginning of the 24 hour copy interval
2) Copy job sees new restore point and copies the restore point
3) Source backup job runs again within the 24 hour copy interval and creates a new restore point.
4) Will the copy job see this new restore point within the interval and copy it?

Will a backup copy job copy more than 1 restore point during its interval? We have daily backup jobs that run each night, each with an associated copy job. The backups start at 8:00 PM and the 24 hour interval is set to start at 12:00 AM. If the primary backup job takes longer than expected and finishes at 1:00 AM one day and before 12:00 AM the next day, we would have two restore points within the 24 hour copy interval. Will both be copied or does Veeam only check once during each interval?

A Backup Copy job creates 1 restore point per copy interval. (If per-vm is turned on in the repository setting, this would of course be 1 restore point per VM.)

The Backup Copy job does not literally copy restore points, but more so uses restore point data from the source to create restore points on the destination.
At the beginning of the interval the Backup Copy job determines if new data is available, if so it will use that data from the source to create a restore point on the destination. If no new data is available the backup copy job will watch for new data to be created on the source. If during the copy interval new data is created, it will only be used if there was no new data at the start of the copy interval.

For example if a customer has a backup job that is set to run every hour, and an associated backup copy job is set to interval once a day. The backup job will create 24 restore points, but the backup copy job will only create 1. That one restore point created by the backup copy job will always be point-in-time, so with this configuration granularity is lost on the destination.

Personally I advise that customers who are matching backup jobs to backup copy jobs to set the backup copy interval to start at the same time as the backup job itself. The reason is if in your example of the backup job set to run at 8PM fails to create a restore point for some reason, then the copy job that intervals at midnight will find no new data. It will then end up waiting till the next backup job run at 8PM. Now the backup copy job has waited 20 hours for new data. If we assume the 8PM backup job completes at 10PM, then this now leaves the backup copy job only 2 hours to try and create the restore point on the destination.
