I’m working on restoring files on a Linux server from a Synology Active Backup. It was going pretty quick for larger files, leading me to think it must check file checksums or something to make sure the file has changed before restoring it. However, once it got to the small files, the checksum checks take more bandwidth than just overwriting with the same file.

Currently 13 hours into the restore and have sent about twice as much data over the network than the original restore size.
