The reason why I am asking because I am looking at the manually and from it appear it is listed under the limitation for per-machine backup files and that it cannot be enable for rotated drives. Now my question if I am using several Synology NAS with rotating disks some with 7200 RPM and some that are 5400 RPM should I be enabling this option? From option description itself, it is suppose to improve backup performance for storage devices that are enterprise grade block storage.
I was review the option for 'Use Per-Machine backup files' on our repositories under the advance options and from what I take it, this option should not be enable if we are using backup repositories with rotated drives.
