Backing Up Clients Using Disk Discovery

How Are Disks If you specify a client backup with disk discovery, Data Protector

Discovered? contacts the client at backup time and finds all filesystems on the disks that are attached to that system. Only mounted disks are identified using the mount command. Then Data Protector backs up each filesystem identified as a regular filesystem, except for NFS, CD mounted filesystems, and removable volumes. The description for each filesystem object is generated and the filesystem mountpoint is appended to the description of the client backup.

When to Use Disk This backup type is recommended under the following conditions:

Discovery

•If you back up workstations with relatively small disks that are frequently mounted or unmounted.

•If you would like to back up the data following a mountpoint into one directory, regardless of how many filesystems are mounted. For example, /home/data, where /home/data/disk1 and /home/data/newdisk/disk2 can be mounted or unmounted frequently and independently of each other.

You can use disk discovery by specifying the client as a data source. If another disk is mounted later, it will be included in the backup.

In contrast to a filesystem backup, where you have to specify any newly added disk or mounted filesystem that is not yet specified in the backup specification, this is unnecessary if you use disk discovery.

To create a backup specification that will define a disk discovery backup, follow the procedure described in “Example of Creating a Backup Specification” on page 155.

Once you get to the Source property page of the Backup wizard, click the check box next to the client. This selects the entire client to be backed up, as shown in Figure 5-7.
