Self-service image-level restore of file systems

You can perform self-service image-level restores of file systems to the original location by using the ddfsrc command. Note that this restore is not supported in the following scenarios:

• When the restore destination is the C:\ volume, which can result in the operating system becoming unavailable.
• When the restore destination is a volume with the File System agent installed.

Before running ddfsrc, use the ddfsadmin backup command to list the local backups for a particular host and obtain the ID of the save set you want to restore. Using the ddfsadmin utility for file systems provides more information about the ddfsadmin backup command.

To restore from a particular backup, specify the ID of the save set as an input to the ddfsrc command, as in this example:

ddfsrc -h DFA_SI_DEVICE_PATH=device path (for example, /fsa2) -h DFA_SI_DD_HOST=Protection storage system IPv4 address -h DFA_SI_DD_USER=Protection storage system username (for example, sysadmin) -S 1551407738 -r file path (for example, /volume1_ext3) -i y.

where:

-h "DFA_SI_DEVICE_PATH=<storage_unit_and_path>"

Specifies the name and the path of the storage unit that contains the backup.

-h "DFA_SI_DD_HOST=<server_name>"

Specifies the name of the protection storage system server that contains the backup.

When you have a remote (secondary) protection storage system server that has replicated databases to restore, type the name of the secondary server. A user on the secondary protection storage system server must be in the same group as the primary protection storage system server.

-h "DFA_SI_DD_USER=<Protection storage system_user>"

Specifies the protection storage system username.

You must register the hostname and the DD Boost username in the lockbox to enable Microsoft application agent to retrieve the password for the registered user.
