Restoring your data
Use Tivoli® Storage Manager to restore backup versions of specific files, a group of files with similar names, or entire directories.
You can restore these backup versions if the original files are lost or damaged. Select the files that you want to restore by using a file specification (file path, name, and extension), a directory list, or a subdirectory path to a directory and its subdirectories.
Note: When
you restore a directory, its modification date and time is set to
the date and time of the restore operation, and not to the date and
time the directory had when it was backed up. This is because Tivoli Storage Manager restores
the directories first, then adds the files to the directories.All client backup and restore procedures that are referenced by this topic also apply to the web client. However, the web client does not provide a Preferences Editor for setting client options.
Attention: Do not restore operating system files, like base system
directories, kernel modules, or patches, to their original location
while the file system is running. The operating system might hang
or crash.The following are the primary restore tasks:
- Restoring files and directories
- Restoring Windows system state
- Restoring Automated System Recovery files
- Microsoft Dfs tree and file restore
- Restoring an image
- Restoring data using the GUI
- Command line restore examples
- Restore data from a backup set
- Restoring data to a point in time
- Restore NAS file systems
- Authorizing another user to restore or retrieve your files
- Authorizing another user to restore or retrieve your files
- Restoring or retrieving files from another client node
- Restoring or retrieving files from another client node
- Restoring or retrieving your files to another workstation
- Restore or retrieve files to another workstation
- Restoring a disk in case of disk loss
- Deleting file spaces
- Deleting file spaces
- Restoring data from a VMware backup
Refer to IBM®
Tivoli Storage Manager for Space Management for UNIX and Linux for details
about restoring migrated files and the restoremigstate option.
- Duplicate file names
If you attempt to restore or retrieve a file whose name is the same as the short name of an existing file, a file name collision occurs (existence of duplicate file names). - Universal Naming Convention names restore
Using a Universal Naming Convention (UNC) name permits you to restore specific shared files to a separate file space. This is useful if, for example, you or an administrator want to restore a portion of data that you would otherwise be unable to access. - Active or inactive backup restore
Your administrator determines how many backup versions Tivoli Storage Manager maintains for each file on your workstation. Having multiple versions of a file permits you to restore older versions if the most recent backup is damaged. - Restoring files and directories
You can locate the files you want to restore by searching and filtering. - Restoring Windows system state
Tivoli Storage Manager supports the Microsoft Volume Shadowcopy Service (VSS) on Windows clients. Tivoli Storage Manager uses VSS to restore the system state. - Restoring Automated System Recovery files
You can restore Automated System Recovery (ASR) files to recover the Windows operating system volume configuration information and system state if a catastrophic system or hardware failure occurs. - Restoring the operating system when the computer is working
If your computer is working, you can restore the operating system from backed up files. - Recovering a computer when the Windows OS is not working
If the computer has a catastrophic hardware or software failure, you can recover a Windows operating system with Automated System Recovery (ASR). - Microsoft Dfs tree and file restore
To restore Dfs junctions and the data for each junction, restore the Dfs junction metadata first and then restore each junction separately. - Restoring an image
There are some items to consider before you begin restoring images on your system. - Restore data from a backup set
Your Tivoli Storage Manager administrator can generate a backup set, which is a collection of your files that reside on the server, onto portable media created on a device using a format that is compatible with the client device. - Restore Net Appliance CIFS shares
Restoring the share definition requires restoring the root directory of the share file space, which under most circumstances can be done as follows: dsmc rest \\NetAppFiler\CifsShareName\ -dirsonly. - Restoring data from a VMware backup
You can use several methods for restoring data from backups to a VMware virtual machine. The restore method depends on the type of backup and on the version of Tivoli Storage Manager client software that you use to run the restore. - Restore Windows individual Active Directory objects
You can restore individual Active Directory objects to recover from accidental corruption or deletion of Active Directory objects without requiring a shutdown or restart of the Active Directory server. - Restoring or retrieving data during a failover
When the client fails over to the secondary server, you can restore or retrieve replicated data from the secondary server. - Authorizing another user to restore or retrieve your files
You can authorize a user on another node to restore your backup versions or retrieve your archive copies. In this way, you can share files with other people or with other workstations that you use with a different node name. - Restoring or retrieving files from another client node
After users grant you access to their files on the server, you can restore or retrieve those files to your local system. - Restoring or retrieving your files to another workstation
When you are using a different workstation, you can restore or retrieve files you backed up from your own workstation. - Deleting file spaces
If your Tivoli Storage Manager administrator grants you authority, you can delete entire file spaces from the server. - Restore an image to file
When you back up an image, Tivoli Storage Manager backs up the first sector of the volume, but when the data is restored, it skips the first sector to preserve the original logical volume control block of the destination volume. - Manage GPFS file system data with storage pools
GPFS™ 3.1 and 3.2 allow you to manage your data using storage pools. A storage pool is a collection of disks or RAIDs with similar properties that are managed together as a group. - Restoring data to a point in time
Use a point-in-time restore to restore files to the state that existed at a specific date and time. - Restore AIX encrypted files
When files are backed up in raw format from an AIX® JFS2 Encrypted File System (EFS), you can only restore them to the same or another JFS2 EFS. They cannot be restored to any different file system, or on a different platform. - Restore AIX workload partition file systems
All the files created by the local workload partition (WPAR) and backed up by the Tivoli Storage Manager client installed at the global WPAR can be restored by the Tivoli Storage Manager client installed at the global WPAR. - Restore NAS file systems
You restore NAS file system images using the web client or command line interface. - Restore active or inactive backups
Your administrator determines how many backup versions Tivoli Storage Manager maintains for each file on your workstation. - Restoring data using the GUI
This section lists the steps to follow to restore backup versions of individual files or subdirectories. - Command line restore examples
This topic lists some examples of restore commands to use for specific tasks. - Restoring Solaris Zettabyte (ZFS) file systems
Zettabyte File Systems (ZFS) use storage pools to manage physical storage. - Additional restore tasks
This section discusses some advanced considerations for restoring data.
