Restoring data from VSS backups

The Microsoft VSS restore process includes the steps outlined in the following topics:

IMPORTANT: The SQL Server® Instance must be stopped when restoring the master database.

Selecting data for a VSS restore

On the Create Restore Job — Choose Saveset page, select Plug‑in for SQL Server from the Plugin Type list.

Full Database

VSS Full

Differential Database

VSS Differential


VSS Copy Only

When you select a saveset, the following details are displayed in the Saveset Information area: Job ID, job title, server name, client name, plug-in name, saveset date and time, retirement setting, Incremental Backup or not, Archive or not, saveset size, and snapshot-based backup or not.
Click Next.
On the Create Selection Set page, select the applicable instance or the database for inclusion in the restore procedure.

Setting VSS restore options

On the Create Selection Set page, click Edit Plugin Options, and configure the following parameters — these options are available for all VSS backup types:

Backup Method: This field displays the backup method used for the selected saveset.
Backup Type: This field displays the type of backup used for the selected saveset.
Restore Method: Select one of the following options:
VSS Restore: Select this option if to complete a restore to the same machine from which the backup was created.
Copy Database Files to Target Directory: Select this option to restore database files to a specified location. You can specify a directory on the local machine where the backups were taken. You can also specify a directory on any machine that has NetVault Backup and the plug-in installed and is reachable from the NetVault Backup Server, even if the machine does not have SQL Server® installed. To restore a VSS backup to a different machine, use the Target Client list to select the NetVault Backup Client of the corresponding target machine.
IMPORTANT: Because the maximum path length in Windows® is 260 characters, check that the combination of the filenames and target path does not exceed 260 characters; otherwise, the restore fails.

If the backup contains FILESTREAM data, the restore process does not retain folder structure; the plug-in restores all files to the same folder. Because the folder structure of the database is not recreated, a file-activation error appears if you try to access the database. To avoid this issue, restore the backup to the original location.
Restore Type: This section lets you specify the action that must be performed after the restore operation. You can select from the following options:
With RECOVERY: Select this option if you do not intend to apply additional Transaction Log or Differential Database backups after the restore of the selected data has completed.
With NO RECOVERY: Select this option if you intend to apply a different Transaction Log or Differential Database backup after this restore has completed.
