Initial Cache Size

The Initial Cache Size property is the initial size for the VSP cache file when creating snapshots.

If the cache file is placed on a volume not being snapped, the Initial Cache Size property is ignored. If the cache file is placed on a volume being snapped, the size for a VSP cache file is at the Initial Cache Size property. The VSP cache file is sized differently, depending on the value used for the Initial Cache Size property and the Customize Cache Size property:

1. If Customize Cache Size is disabled, NetBackup automatically determines the initial cache size for the VSP snapshot if the cache file is being placed in the volume that is being snapped.
2. If Customize Cache Size property is enabled, NetBackup uses the user specified size in the Initial Cache Size property. If the VSP cache file is placed in the same volume as the volume being snapped, the cache file size will be as follows:
   • A percentage of used disk space of the source volume based on the Initial Cache Size property if the form of measurement selected is Cache Size in % of Disk Space.
   • The value in megabytes specified in the Initial Cache Size property if the form of measurement selected is Cache Size in MB.

If the cache file is not placed in the same volume that is being snapped, the Initial Cache Size property is ignored.

This property appears for Windows clients only.
