I have a larger disk image (sparsebundle) that I want to incrementally sync between 2 macs. iCloud can’t do block level syncing so if one thing in this disk image changes, it would re-upload the entire thing.
Dropbox can do block-level syncing, but I don’t want to add another monthly subscription just for syncing this one file.
Is there other software that can be used for this? Maybe even just on the local network as a workaround?
This article (How to sync, share and transfer files from Mac to Mac) on SetApp recommends ChronoSync but I’ve never heard of it before either.
