Answer) Backup jobs performed by AhsayOBM on a Synology NAS can be slower because there are fewer resources available in comparison to a desktop or server-grade computer.
Typically, on most NAS devices, there is less memory and CPU processing power available for compression, encryption, and delta generation during a backup.
