==== Performance ====

It is hard to predict how much time a backup job needs to complete. It depends on the number of files, the total file size, the file changes since last run, the network speed and not least on the CPU power, disk speed and RAM of the source and backup server. The following table of measured values will give you an idea of what you can expect.

'''Note:''' The last action of a job run is to remove the oldest backup, e.g. if archive scheduled.11 exists and you have set the scheduledKeep property to 12, then it must be deleted. This can take a significantly long time, which increases the total job execution time.

A affa --rise run on a SME 7.2, 40 GB data, 411.500 files, 2x2.8 Xeon CPU, 1GB RAM, SW-RAID 5 with 4 U320 SCSI drives took 7 minutes including the final reboot.
