Advanced Backup to Disk Performance White Paper

Observations

HP ProLiant DL380 G4 Server

The highest average CPU load (84%) occurred during the small file restore (22 million) from Ultrium

960, which was caused by the slow Windows NTFS. Please check the figure below and

Table18.

The highest memory usage occurred during the Advanced Backup to Disk of small files. One backup

process (bma.exe) allocated 35 MB and all backup processes together approximately 100 MB,

which can be considered as low. The page file size increased up to 700 MB.
