Re: Seeding a Repl job with an excluded disk

Possible this could be submitted as a feature request? Allow replication to check disks selected vs backup disks selected and perform successful seed based on matching omitted disks?

Yes, thanks for the feedback, meanwhile Tom's workaround is still the best way to address this scenario.

[MERGED] Partial replication from backup job with excluded d

Post by fll » Oct 30, 2017 10:10 am

Hello, we need to know if a backup job of a virtual machine with excluded disks can be used for a replication job with the replica seeding option enabled. It seems that it is not so ('Backup file does not contain all VM disks and can not be used as a seed').
Is it necessary to perform a full backup job including all drives to perform a partial replication of the virtual machine or is it possible to add the missing drive to the backup job in order to do partial replication?

Thank you.

Hi,

You can do that if these disks will be excluded in the replication job settings for the particular VM too. Thanks!

Hi,
I have repeated the process:
1.- Generate a backup job that includes only the system unit of the virtual machine, but not eliminating it from the configuration if it can be included later in the replication.
2.- Generate a replication job with the replica seeding option activated, selecting the system unit (as in backup job) and the option "Source Repositories" configured in "From backup files".

When you launch the replication job it fails and shows the following error:
"Backup file does not contain all VM disks and can not be used as a seed".

Thank you.

Hi,

Did you exclude the same disks in the replication job on the Virtual Machines step -> Exclusions -> Disks?
The error you've mentioned tells you that you are trying to replicate more disks than the backup seed contains. Thanks!

In both cases I choose the option "System disk only"

Thank you.

Is there any chance you have another backup with the mentioned VM without disk exclusion in the repository that was picked for seeding? Thanks!

No, in the repository there is only the backup that we are talking about. There is nothing else.
Thanks!

Hello, there was some misunderstanding between Dmitry and QA, it is not actually possible to use backup with excluded disks for seeding. However, what you could do to seed is change the source of the replication job to the corresponding backup file (replication from backup), make sure exclusions are configured similarly to the source backup job, and perform initial replication job run, then switch replication job source to the original VM back (preserving exclusions). In this case replication job will be seeded and continue normally.

Hello, in fact, using the corresponding backup file as source of the replication job, with the same exclusions in the backup job and the replication job, the replication ends correctly.
Will a faillback from a replica with exclusions eliminate the excluded units in the original machine?
Thanks!

No, original VM disks will be left as they are.
