Remote Sync

[stormtronix]

I tested remote sync today, setup a similar server to the pbs - first of all I ran into the same mistake as mentioned in another post:

on the PBS I configured the "remote" and afterwards the sync, which removed all my (test)Backups under a second

It must be clear that the remote and sync has to be configured on the target machine and not on the source



now to my question:

after repeating some backupjobs, which where only between 50 and 300 MB thanks to dirty-bitmap the sync was repeated and according to its output no data was changed - is this output correct? How can I be sure that the dirty bits were synced?

if it says

2020-07-16T16:07:27+02:00: re-sync snapshot "vm/384/2020-07-16T13:45:12Z"
2020-07-16T16:07:27+02:00: no data changes
2020-07-16T16:07:27+02:00: re-sync snapshot "vm/384/2020-07-16T13:45:12Z" done

than that snapshot was already fully synced.

if it says

2020-07-16T16:07:27+02:00: sync snapshot "vm/4102/2020-07-16T14:05:02Z"
2020-07-16T16:07:27+02:00: sync archive qemu-server.conf.blob
2020-07-16T16:07:27+02:00: sync archive drive-virtio0.img.fidx
2020-07-16T16:07:27+02:00: got backup log file "client.log.blob"
2020-07-16T16:07:27+02:00: sync snapshot "vm/4102/2020-07-16T14:05:02Z" done

than that snapshot was new and synced. this output could surely be improved to give more indication of what's going on
