Backup is supported to a server with a hard disk of 160GB or larger. The actual portion of that space, the backup quota, available for backup usage can be checked using the process below. On servers with a smaller hard disk, no backup quota is supported.
Estimating the Backup Quota
The approximate space that will be allocated for the backup quota can be calculated as follows:
Backup Quota = (0.8 x Hard Disk Capacity) – 92GB if the Hard Disk Capacity is greater than 160GB, otherwise zero.
The capacities are all approximate. The quoted disk capacity from a disk manufacturer or a virtual server platform will differ from the capacity reported by the operating system.
For example: For a 500GB hard disk, the backup quota is approximately 308GB.
Checking the Backup Server’s Backup Quota
Once a server is installed, the actual space allocated for backups can be checked as follows:
Login to the backup server's web manager menus.
Click and select Platform View.
On the System tab, note the Quota available for backup data value. Note this is the total space usable for backups, it does not account for the space already used by any existing backups.
