Copy Backup Jobs

[NZamp]

Hello to all,

i´ve got an implementation of new cubes at a customer site. Now i would like to copy the existing backups to the new federation. From the gui it is possible to copy the jobs but only one after another. Selecting more backup jobs doen´t give you the menue point "copy backups". With the cli it is also not to comfortable because the use of wildcarts is very limited so are my abilities to write a script.

I once had a copy backup script from SimpliVity that did the job but with the version 3.7.x it doesnt work anymore.

Could someone please tell me an easy way to copy the backups to the new federation? Any help is appreciated

Cheers,

Nick

It's not possible to copy backups between federations but you can between clusters.you can certainly copy single backups but that is not great option if you have thosands of backups.

Is the original cluster being decommissioned ?


Probably best to open a support case a script should exist.

@NZamp, The script that @DaveOb is referring to is this one:

#!/usr/bin/env python
'''
This script will move VM backups from one cluster to another, VM-by-VM.

USAGE: ./backup_move.py --vm <vm> --datastore <datastore> --source_cluster <source_cluster> --destination_cluster <destination_cluster>

Hello Scott,

the script works on machines that are still running on the old cluster. The backups are copied with no problems but when i try to copy a backup of a machine that is already migrated, i get the error "ERROR [10]: Unknown VM or VM not found in datastore or VM not stored by SimpliVity.". When i use the gui i can copy the backups without a problem.

Cheers,

Nick
