I currently use Time Machine to backup to my NAS. I'd like to setup offsite backup of my Timemachine sparsebundles to Backblaze B2, but I'm confused by all the varied ways this could be setup.
HBS3 offers two options - Backup and Sync. My broad understanding of the difference between a backup and a sync service would be that backup just adds to the destination and sync keeps them both in sync. However because of the options provided for each of these in HBS3, it's very hard to determine the difference and which is more appropriate for each purpose
Backup offers:
- with or without version management
- qudedup - a facility to optimise transfer size and speed, but make the backup location unreadable as a conventional folder structure
- Remove deleted data from desitnation - sounds very much like sync to me
- one way sync - (sounds like backup)
- two way sync - (sounds like sync)
- active sync - (not sure what this is)
each of the sync options then gives sub options to:
- Mirror - (sounds like sync)
- Copy - (sounds like backup)
- Move - (sounds like backup)
- No option to use qudedup as far as I can see
- Backup task (not sync)
- qudedup on - as the sparsebundle is itself not browsable, so doesn't matter if converted to something else unreadable
- Remove deleted data - so it works much like a sync and the B2 backup doesn't balloon in size with every large change that happens in my TM backup
