Writing a backup to the s3 mirror local source while the mirror is running

[frank-s]

On the subject of xo backup, can someone tell me what will happen or how xo will handle a new backup being written to the source whilst the mirror to s3 is still running? The source is receiving delta backups locally and the mirror is a mirror incremental backup to s3. Will xo handle this gracefully? I am using xo from sources fully patched.
Thanks.

@frank-s ensure you are using the merge backup synchronously in the source job

(in the backup job advanced)

You may have some error regarding lock if the VM is used by both, the backup job will skip this VM an retry later.

So you will have some errors, some VM may be skipped on some job, it won't break the backups

@florent Thank you.
