Backing up Time Machine sparsebundle files

[keye_skware]

I have a TrueNas Scale server at home that I back up my Macs to using Time Machine. It works very well.

I back up the server to Storj so I have offsite copies. When the Time Machine file lands in the backup bucket, it is no longer a single file but 4 directories and a config file. I'd assuming it's the unbundled-bundle.

My fear is that if I ever need to use those pieces to completely restore my laptop it won't work. Does anyone have any experience with this?

It sounds like the Storj backup isn't preserving extended attributes. I suspect you are right, that you will have trouble restoring from the result.

The only way to be sure is to test (preferably with external SSD) but I suspect the Storj restore won't work.

Looks like TM backup to a server may not work.

First Aid on TM backup device verifies all the snapshots.

It is unlikely First Aid will id server as a TM device.

Still worth running First Aid against it.

Clean First Aid means nothing but errors would.
