So I’m currently doing a regular NAS to USB backup (synchronize) and it works great. First backup took a while, subsequent ones are fast. No problem there.
What I’m wondering is, if I try to do a restore in the future what will happen in the scenario that I’ve accidentally deleted content on the NAS and I try to use the Restore Backup function to restore that data.
My assumption is that it will try to synchronize from USB to NAS when I do “Restore Backup” and it will copy/restore and files from the USB drive not found on the NAS (due to deletion) and leave unchanged files alone (so should be fairly fast).
Is that a correct assumption?
