Recovery Performance Disappointing
yesterday I performed a recovery of a Windows 2008R2 test system (~400GB) from a NAS and it took hours (>6h) to finish the recovery. Both, the server and the NAS are normally capable to saturate the GbE link. So I started a second test and recovered my Desktop System (SSD and Backup an a SATA attached HDD) an the result was equally. It took over a hour to recover a system with ~70GB of data.
Both backups were differential backups with normal compression. While the backup speed is really impressive the recovery time is absolutley inacceptable - especally when you have to revocer a server system.
Whats the reason for this poor recovery performance?
