Overview

The following page describes the agent-specific restore options. Additional restore options are accessible from the Related Topics menu.

For NetWare File System and NDS iDataAgents, restore operations can be performed from the client, iDataAgent, and backup set levels in the CommCell Browser. The Novell GroupWise iDataAgent, however, does not support the use of backup sets and only performs restore operations from the iDataAgent level.

When there is a problem with the NetWare server, GroupWise server, or the operating system of the client computer, full system restores may be required. See Restore Data - NetWare Server - Full System Restore for more information.

The following restore operations are supported by the NetWare Server iDataAgents:

The NetWare File System iDataAgent allows you to restore file system data to:

the original path
a different path on the same NetWare server
a different NetWare server in the same tree
a different NetWare server in a different tree

The NDS iDataAgent allows you to restore NDS containers and objects to:

The original path within the same NDS tree, using the same NetWare server from which the data was backed up
The original path within the same NDS tree, using a different NetWare server than that from which the data was backed up

You cannot restore an NDS container or object to a different tree.

The Novell GroupWise iDataAgent allows you to restore GroupWise databases, user accounts, mailboxes, and messages to:

a different path and/or client from which the data originated (recommended)
the same path/Client computer in the CommCell

Restore Considerations for This Agent

Before performing any restore procedures for this agent, review the following information.

All NetWare Server iDataAgents:

Review the general restore requirements described in What You Need to Know Before Performing a Restore.
In addition to the NetWare server being powered on, the galaxy.nlm must be loaded.
Do not set a quota for an object (such as a volume, directory, or user) that is lower than the amount already used. Doing so may cause improper results for data protection or recovery operations.

NetWare File System iDataAgent:

To restore File System data, you must have Read/Write/Modify/Erase/Create/File Scan rights to the container object to which the content will be restored.

NDS iDataAgent:

To restore NDS data, you must have Admin rights to the container object to which the content will be restored.
When browsing NDS data with a specific page size configured, the browse results will not reflect the selected page size; rather, all data is displayed on a single page.
When restoring on NDS, all parent containers in the object's path must exist on the destination tree. NDS objects cannot be restored if their parent does not exist.
NDS objects are always restored to their original location in the NDS tree.
There is a bug in Novell's tsands.nlm on NetWare 5 that causes it to back up alias objects as the object they pointed to instead of as the alias objects themselves. For example, an alias object for a volume object is backed up as a volume object. When restored, the alias object will not be restored, but instead the volume object will be restored.

Novell GroupWise iDataAgent:

Restores for GroupWise behave differently than that of the other NetWare iDataAgents. GroupWise iDataAgent restores will always unconditionally overwrite any data already existing at the restore destination. For this reason, unless you are restoring your GroupWise system completely, it is strongly recommended that you either:

Restore GroupWise data out-of-place to a configured restore area. (For step-by-step instructions, see Restore Out-of-Place, Cross-Platform or Cross-Application.)

Configure your restore area to point to the destination path of the restore once the job has completed successfully. A restore area is a location where restored GroupWise data can be retrieved if lost. These restore areas can be configured using ConsoleOne. (Refer to the GroupWise documentation for instructions on this procedure.)

When configuring your restore area, keep in mind that any directory name within the path should not exceed more than 8 characters (as per the DOS naming convention). If a directory name exceeds 8 characters, the GroupWise client may produce error messages indicating the path is either invalid or does not exist while trying to retrieve lost items. For example:

SYS:\RestoreArea is considered an unacceptable path name

SYS:\GWRest is considered an acceptable path name

If restoring GroupWise data with all entities selected, the databases must be restored in-place.
It is best practice to restore GroupWise databases out-of-place and then use the GroupWise utilities to point to the area you restored the data to. Whether you need to restore one mailbox or an entire GroupWise system that was lost, restoring the data out-of-place and then using tools such as ConsoleOne is recommended rather than restoring databases in place.
Single user accounts and mailboxes may be restored using ConsoleOne providing all subclients have been successfully backed up using the Novell GroupWise iDataAgent. For step-by-step instructions on restoring a single user account and mailbox, see Restore a Single GroupWise User Account and Mailbox.

Restore Tips

Keep the following details in mind when restoring data:

Perform an image browse if you need to preserve the directory structure of the data you want to restore.
Perform a no-image browse if:
- You do not need to preserve the directory structure of the data you want to restore.
- You want to restore files that have been deleted from the client computer and therefore not included in the most recent backup.
The unconditional overwrite option restores data to the destination directory even if files of the same name already exist.

Restore NetWare Data to a Protected Directory

For NetWare File System iDataAgent, access to NetWare files and directories is controlled by a set of access privileges called trustee rights. To create a file or directory, you need Write and Create rights to the parent directory. Similarly, to restore data, these same rights are required.

When you restore file system data, the File System iDataAgent restores the data using the NetWare user account on the destination computer that was assigned. The identity of this account is revealed by the General tab of the File System iDataAgent property box. To ensure that data can be restored to any path, we recommend that this account be assigned the Supervisor right. If however, the Supervisor right is not, and for your own reasons must not be, granted to this account, and you want to restore data to a directory to which the account does not have the necessary rights, you can still restore the data using the Impersonate NetWare User restore option. Using this option, you can restore data to a directory to which the account has insufficient trustee rights.

For step-by-step instructions on restoring NetWare data to a protected directory, see Restore NetWare Data to a Protected Directory.

Restore NetWare Server Specific Information

The system allows you to restore the Server Specific Info package, which contains configuration information on a NetWare server. This information can be important if you need to recover an entire NetWare server. Specifically, the package contains:

SERVDATA.NDS
DSMISC.LOG
STARTUP.NCF
AUTOEXEC.NCF
VOLSINFO.TXT

For information on each of these files, see your Novell NetWare documentation. When you restore the data, the system writes it to the following path on the destination computer:

SYS:\SYSTEM\<source_server_name>.

For step-by-step instructions on restoring NetWare Server specific information, see Restore NetWare Server Specific Information.

Restore Single E-Mail Messages

Although the GroupWise iDataAgent will only restore entire databases, you can use the GroupWise client to retrieve individual messages. Once the admin has restored the databases to the configured restore area, users will be able to browse this area the same as they would their regular mailbox. From there, they will have the ability to pick and choose what missing messages they would like to restore.

Restore Destinations

NetWare File System and NDS iDataAgents:

By default, the NetWare iDataAgents restore data to the client computer from which it originated; this is referred to as an in-place restore. You can also restore the data to another Client computer in the CommCell. Keep in mind the following considerations when performing such restores:
- The destination client must reside in the same CommCell as the client whose data was backed up.
- Note that when you perform restores other than in-place restores, the restored data assumes the rights (i.e., permissions) of the parent directory. (Trustee rights in the case of NetWare File System.)
- When restoring file system data it is possible to restore across different namespaces, as long as the filenames fit where the data will be restored. When restoring multiple objects, the restore will fail if any of the objects has a longer name than the available namespaces allow. The restore will not fail if you select the Ignore Namespace Requirements option in the Advanced Restore Options dialog, which allows those files whose filenames are valid for at least one of the available namespaces to be restored; however, those files whose filename are not supported by the available namespaces are not restored. To avoid this issue completely, it is best to ensure that all namespaces required for the restore are available on the destination drive.

Novell GroupWise iDataAgent:

By default, the GroupWise iDataAgent restores data to a different path and/or client from which it originated; this is referred to as an out-of-place restore. You can also perform an in-place restore, which restores the data to the same path/Client computer in the CommCell.

It is strongly recommended you restore the data out-of-place to prevent the overwriting of new data that may have been produced since the last backup.

The following section enumerates the types of restore destinations that are supported by the NetWare iDataAgents. See Restore/Recover/Retrieve Destinations - Support for a list of Agents supporting each restore destination type.
