Backup Copy of a Backup Copy

[adrenaline_x]

I have a situation where i need to make a Backup copy of a Backup copy.

After alot of reading i see that the only way to really accomplish this is by using a periodic copy Backup copy job and then select the initial backup copy target as the source for the VMS i want to copy.

Our setup is we have 2 Identical backup sets each going to a different 100TB windows server. One Backup Set and its corresponding Target repository is disabled/physically disconnected (air gapped) from the network every other week (swapped). There are 2 identical backup copies jobs that copy the Backup from the target repository to a data domain (different mtrees/storage units)

We now need to transfer another copy of the data on the data domain to another datadomain at another location. We were doing this with dd replication but the visibility and management of files isn't ideal/workable.

This works alright, but the issue is the 4 servers i'm trying to copy now are rather large at 4-20tbs in size and using periodic copying (1 day) causes the backup to stop at 24 hours and restart/resume. You would think this would be fine, but during the initial 24hours the vms are reading/moving at 24 MB/s and after it restarts is then sits at 6MB/s and when it restarts again is will be even slower.

Normally all our backup copy jobs are set to immediate copy so that they run until the backups are copied but there is no way to accomplish a backup copy of a backup copy.

I understand in normal situations we would just copy the backup data in the initial repository and just copy it to two different locations but the storage repository can not handle all that traffic.

So.. is there a better way to accomplish what we are trying to do or is there a way to set this up with immediate copy?

Hello,
I see no better way than you describe. Without spoilering too much of V12 backup copy job changes... I would stay with the data domain replication in this scenario.
