+==== Network Requirements ====
+Recommended minimum network speed is at least 100Mbps download speed.
+The network bandwidth requirements will increase in proportion to the size of the compressed file/image and or the incremental delta chain length to ensure optimal performance. Working with limited network bandwidth may severely affect the granular restore performance.
+You can use an online network speed test website (e.g. [[http://www.speedtest.net|speedtest.net]]) to get an idea of the actual bandwidth of the machine.
+==== Permissions ====
+The Windows login account used for installation and operation of the AhsayOBM client machine requires Administrator privileges.
+==== Other Dependencies ====
+The following dependencies are restore related and therefore they will be checked by AhsayOBM / AhsayACB only when an OpenDirect restore is performed. Absence of these elements will not affect the backup job but would cause the restore to fail.
