hi @ricky222
the structure of the backup repository is documented here https://github.com/vatesfr/xen-orchestra/tree/master/%40xen-orchestra/backups/docs/VM backups .
Checking if a backup is done/running can be done with the XO rest api from https://xen-orchestra.com/docs/restapi.html
You can go confidently with rsync/rclone for the full backups ( the xva files ). For restoration you can even use the import VM function of XO or xo-cli to directly import the xva. If you rsync data back from rsync to a local backup repository, you must delete the local cache.json.gsz to ensure XO see the downloaded backup (xva + hash + json)
The caveat is for the incremental backup and the merging. In XO we are merging older incremental backups, that means modifying older files. This process is offloaded to another node process which does not appear for now in the api. Making a transfer during a merge may lead to an invalid backup on target.
Do you have enough informations ? Also, it could be great if you share your setup when you have a working/tested setup with rsync
Regards
