HB is not 100% best solution when you want to use it with ABB (or any ABXXX package). It can work, but there are certain scenarios that it is best to focus on Snapshot Replication as your ABB backup method.Do I understand correctly that this is not advised?
SR is required on both source and destination as it is BTRFSI assume this is needed?
nothing that will be 100% secure and accurate as SRAny other suggestions to make an offsite backup of ABB data?
Synology Drive would be one way, or the new C2 Backup (cloud) solution by Synology. Essentially it is ABB in the cloud but for a PC level it will work just fine. Also C2 Backup will not be just a file level backup, but as I said, an ABB alternative meaning you will have bare-metal restore options of the whole PC if needed.Synology Drive?
If you are sticking to your on-premise devices, like your NAS, then Drive Server with a pc Drive client will allow you both sync and backup file level scenarios.
