Setting Up Reservation Manager › Post-Installation Configuration › Configure Snapshots

Configure Snapshots

Reservation Manager lets the administrator configure the following features for services:

• Check for free space before taking snapshots.
• Specify growth percentage.
• Specify percentage of space reserved for managing snapshots.

Note: Reservation Manager permits one snapshot at a time. When you take a new snapshot, any previous snapshot is deleted so that there is enough space for the new one. This includes any snapshots created directly from vCenter or vSphere.

To configure snapshots

1. Log in to the Reservation Manager using the CA Server Automation administrator user credentials.

   The home page opens.

2. Click Administer Your Reservation Manager.

   The Administration page opens.

3. Click Manage your configuration settings.

   The Configure Settings page opens.

4. Click the following links in the Virtual Machines area. Each one opens a dialog in which you can change the value and click OK.

   Check For Free Space on Snapshot

   Specifies whether to check for sufficient disk space before taking snapshots.

   Default: true (checking is done)

   Filesystem Growth Allowance for Snapshots

   Specifies the percentage of potential growth for snapshots. For example, if disk space on a VM is 5 GB, and the value for this option is 20 (the default), one snapshot is allotted 1 GB of disk space on the ESX server. This option is useful only when Check For Free Space on Snapshot is true (the default).

   Default: 20 (percent of allocated disk space for VMs)

   Manage Snapshot Reserve

   Specifies the percentage of space reserved for managing snapshots.

   Default: 10 (percent of total capacity per host)

   The configuration changes take effect when the next snapshot is taken.
