Setting Restore Default Destination Options

Restore Destination Options control how behaves during a restore operation when it encounters certain situations involving files and nodes.

To check the default restore destination options or edit default restore destination options:

  1. Open the Configure Defaults window by selecting Configure from the Function Tab bar and clicking Defaults.

  2. Expand the Restore options.

  3. Click the Destination icon or name to select it. The selection is indicated by the selection check box next to the option icon, and the Restore Destination Options dialog appears.

  4. Optionally enter or revise each field:

  • Existing File Handling

    Tells DPX how to behave if it finds a file at the destination with the same name as the file that it is restoring.

Skip Existing Files and Directories

Does not write over the existing file or directory if it has the same name as the one being restored.

Replace Existing Files

Restores the file to a temporary file, ensures that the restore is successful, and then writes over the existing file with the like-named file being restored.

Replace Existing Files and Directories

For existing directories, restores directory characteristics only, such as date, time, and owner. For existing files, restores file to a temporary file, ensures that the restore is successful, then writes over the existing file with the like-named file being restored.

Delete Existing Files Before Restore

Deletes the existing file before restoring the like-named file. Use this option when disk space limitations prohibit using Replace Files.

Rename Restored Files

Renames the file being restored to a name derived from the existing file. On NTFS and UNIX, DPX appends .R01 to the filename. If filename.R01 exists, DPX uses .R02 and so on. On FAT, a file extension of R01 is used. For example, file ABCD.TXT is restored as ABCD.R01. If ABCD.R01 exists, ABCD.R02 is used, and so on.

  • Missing Directories

    Controls how DPX behaves if it tries to restore a file to a directory and discovers that the directory does not exist.

Use Full Privileges

Uses the file privileges the file possessed when it was originally backed up.

Use Parent Privileges

Applies the file privileges of the parent directory into which the files are being restored.

Use Root Privileges

Applies the file privileges of the root directory into which the files are being restored.

  • Destination Path

    Destination Path determines whether DPX retains the original tree structure when you restore to a new location.

Absolute Path

Retains the original tree structure. For example, if on a Windows machine you backed up C:\NewPrjs\Dev\Bin, and restore to C:\NewPrjs\Test, the absolute destination path is C:\NewPrjs\Test\NewPrjs\Dev\Bin.

Relative Path

Removes the parent directories and puts the file in the new restore directory. For example, if on a Windows machine you backed up C:\NewPrjs\Dev\Bin, and restore to C:\NewPrjs\Test, the relative destination path is C:\NewPrjs\Test\Bin.

  • Skip Incomplete Files

    If a file is partially restored, this option specifies whether or not to keep that file.

No

Keep the partially restored file.

Yes

Delete the partially restored file.

The next three fields apply to restoring Exchange.

  • Exchange Point-in-Time Recovery

    Controls whether Restore will delete Exchange logs to restore Exchange to a point-in-time.

Yes

DPX will delete existing transaction logs before restore and then perform a point-in-time restore, which brings the database back to the state when it was backed up. This option is commonly used when you are restoring a backup instance that is not the latest. This option is strongly recommended whenever a restore is needed to nullify an incorrect or maliciously altered transaction.

No

This is the default. DPX will not delete existing transaction logs before restore. DPX performs an up-to-the-minute restore by retaining the existing transaction logs and rolling forward all new transaction from the existing logs. This option is commonly used when you lose a database without losing its transaction logs and you choose to restore from the latest backup instance.

  • Restart Exchange Service

    Controls whether the Exchange Service is restarted when the Restore is complete.

Yes

Restart the Exchange Service after the restore.

No

The Exchange Service is not interrupted by .

  • Exchange Handling

    Determines how Exchange databases are handled after restore completes.

Commit Restore and Mount Database

This is the default. After the restore completes, commit the changes (transaction logs) to the database and mount the Exchange database. The Exchange administrator does not have to manually intervene before the database is available for clients.

Commit Restore Only

After the restore completes, commit the changes (transaction logs) to the database but do not mount the Exchange database. The Exchange administrator will need to manually mount the database to make it available to clients.

Do Not Commit Restore

After the restore completes, neither commit the changes to the database nor mount the exchange database. The Exchange administrator will need to either commit or rollback the changes (transaction logs) and mount the database for use.

Note. DPX does not support restoring the master and model databases to a new location because it is not supported by SQL Server.

  • MSSQL New Location

    Enter the name of a new location where you want to restore a SQL Server database.

  • MSSQL New Location Logs

    Enter a directory path to restore the transaction logs to a different location than that specified in the MSSQL New Location field. If you do not specify a directory, the transaction logs will be restored to the same location as the database.

  • MSSQL Standby

No

Do not restore a SQL Serve database to a standby server. The default is No.

Yes

Restore a SQL Server database to a standby server.

  • MSSQL Standby Undo Directory

    SQL Server creates an undo directory when a database is restored to a standby server. If you do not specify a directory, undo files will be created in the in the product-directory/logs directory.

  • MSSQL With Replace

    When restoring a SQL Serverdatabase that exists, SQL Server performs tests to ensure that it is the appropriate place to restore the data. These tests are not always accurate and sometimes cause a restore to fail.

No

Performs tests before overwriting an existing database.

Yes

Overwrites an existing database without tests.

  • Mount Point Handling

    This field determines how restores data backed up through a Windows 2000 volume mount point. It specifies both where restores data and whether volume mount points are reassigned.

    To back up data through a volume mount point, you must set the Back Up Content of Mounted Drive field to Yes in the Set Job Source Options (see the source option Back Up Content of Mounted Drive for more details). Then, for example, if C:\mnt\driveD was a volume mount point to D:, you would have selected C:\mnt\driveD for backup rather than D:.

Restore Data (no Mount Point)

DPX does not restore a volume mount point. If a directory that was a volume mount point at backup is a volume mount point at restore, data is restored to whatever volume (drive) it now mounts. Otherwise, data is restored not to another volume, but to the directory that was a volume mount point at backup.

Restore Data and Mount Point; Skip Existing Mount Point

DPX reestablishes a volume mount point and restores data to the volume it mounts. However, if a directory that was a volume mount point at backup mounts a different volume at restore, the mount point is NOT reestablished. Data is restored to the volume it now mounts.

Restore Data and Mount Point; Replace Existing Mount Point

DPX reestablishes a volume mount point and restores data to the volume it mounts. If a directory that was a volume mount point at backup mounts a different volume at restore, the original mount point is reestablished. Data is restored to the original volume. For a reconstructive restore, this option is always used.

Note. If a directory that was a volume mount point at backup is a normal directory containing local files at restore, the volume mount point cannot be restored. In this situation, data is restored not to another volume, but to the directory that was a volume mount point at backup.

Note. When performing a Reconstructive Restore, automatically uses Restore Data and Mount Point; Replace Existing Mount Point no matter what setting you choose.

The following table contains an example that illustrates the effect of this field, under various circumstances. Where C:\mnt\driveD is a Volume Mount Point to D:\ during backup. Data is backed up by selecting C:\mnt\driveD while the Back Up Content of Mounted Drive field is set to Yes on the Set Job Source Options dialog box.

Option 1 Restore Data (no Mount Point)

Option 2 Restore Data and Mount Point; Skip Existing Mount Point

Option 3 Restore Data and Mount Point; Replace Existing Mount Point

At Restore, C:\mnt\driveD is still a volume mount point to the same volume D:\

Data is restored to D:\.

Same as Option 1

Same as Option 1

At Restore, C:\mnt\driveD is an empty directory that is not a volume mount point to anywhere

Data is not restored to D:\. Data is restored to C:\mnt\driveD, which no longer is a volume mount point to D:\, but now contains the data that was on D:\.

Data is restored to D:\. C:\mnt\driveD is reestablished as a volume mount point to D:\.

Same as Option 2

At Restore, C:\mnt\driveD is not a volume mount point to anywhere, but is a normal directory containing local files

Data is not restored to D:\. Data is restored to C:\mnt\driveD, which no longer is a volume mount point to D:\, but now contains the data that was on D:\.

Same as Option 1

Same as Option 1

At Restore, C:\mnt\driveD does not exist

Data is not restored to D:\. C:\mnt\driveD is created. Data is restored directly to C:\mnt\driveD.

Data is restored to D:\. C:\mnt\driveD is created and established as a volume mount point to D:\.

Same as Option 2

At Restore, C:\mnt\driveD is a volume mount point to E:, a different volume

Data is restored to E:\, the new volume mount point. C:\mnt\driveD remains a volume mount point to E:\.

Same as Option 1

Data is restored to the original volume D:\. C:\mnt\driveD is reestablished as a volume mount point to D:\.

Note. DPX keeps track of both volumes and drive letters, so if drive letters change, data is still restored to the correct volume.

  • Restore Disk Quota

    Using disk quotas, administrators can limit the amount of data each user can store on a Windows 2000 NTFS or NSS volume. This field determines whether to restore disk quotas.

No

Disk quota settings are not restored.

Yes

Disk quota settings are restored.

Note. It is not necessary to back up an entire volume to back up disk quota settings. Any backup from a supported volume automatically backs up this information. Restoring disk quota settings does not require restoring an entire volume.

If you restore to a new location, disk quota settings are only restored if the new location is the root directory of another like volume and Destination Path is set to Absolute Path.

  • SYSVOL Handling

    If the Enterprise has more than one domain controller, you can choose whether to replicate SYSVOL files and folders to the other controllers as part of the Windows 2000+ System State restore.

Authoritative Restore

Restores SYSVOL files and folders in a primary manner and forces that data to be replicated to the other primary domain controllers.

Non-Authoritative Restore

Restores SYSVOL files and folders locally and allows that data to get updated via the normal replication process. Non-Authoritative Restore is the default.

Warning! When there are replication partners, selecting Authoritative Restore can result in unexpected behavior.

To perform an authoritative restore on the Active Directory, you must run the Microsoft Ntdsutil utility after you have restored the System State data but before you restart the domain controller. For more information about the Ntdsutil utility and authoritative restore, refer to your Microsoft documentation.

  • Cluster Handling

    If your Enterprise contains clusters, you can choose whether to restore the cluster quorums as part of the Windows 2000+ System State restore.

Do Not Restore Cluster Quorum

DPX does not restore the cluster quorum. Do Not Restore Cluster Quorum is the default.

Restore Cluster Quorum

DPX restores the cluster quorum. However, if other cluster nodes are active or if the cluster quorum has changed since backup, the cluster quorum restore may terminate.

Restore Cluster Quorum (Force the Recovery)

DPX restores the cluster quorum even if other cluster nodes are active or if the cluster quorum has changed since backup. Any changes made to the cluster quorum after the backup will be lost.

  • Restore Security

    Determines whether DPX restores security information associated with each file or folder.

Yes

Restores security information. Yes is the default.

No

Security information in the restore destination directories does not get overwritten as the result of a restore job.

The Restore Security option applies to the following items: • Windows NTFS - Security in Properties • UNIX and Linux - Access Control List (ACL) • NetWare, OES NetWare, or OES Linux using NSS file system- Trustee

  • Retry Failed File

    Determines how to handle files that fail when you attempt to restore them. This is applicable only for Windows.

No

Do not retry failed files. No is the default.

Retry Open File

Retry open files only. To use the restored files, the user must reboot after the restore job has completed.

Retry All Failure

Retry all failed files including open files. To use the restored files, the user must reboot after the restore job has completed.

  • NDMP Recover Mode

    Determines the type of recover operation to perform in NDMP restore tasks.

Extract

Only the selected files and/or directories are restored.

Direct

Direct Access Recovery (DAR) is performed. Select this option only if the NDMP server supports DAR.

True Image

Rebuilds an entire file system or subtree if base and incremental backups are restored in order.

  • Enable NDMP Server Logging

    Controls the routing of NDMP server-generated log messages to the job log file.

Yes

All NDMP server log messages will be routed to the master server’s job log file. Yes is the default.

No

The NDMP server log messages will be logged locally in the NDMP client node log file instead of in the master server’s job log file.

  • Additional NDMP Environment

    This option allows you to introduce any additional NDMP environment variables that are necessary for the backup task. Specify your environment variables as an ASCII string with an environment variable name and value pairs using the following syntax:

    env1name=value,env2name=value,...

    Note that syntax validation is not performed on the specified value at job definition time, but rather at run time. Only valid entries are added to the NDMP operation environment. Do not specify any of the following NDMP environment variables in your variable string because DPX controls these specifically:

    • BASE_DATE

    • DEBUG

    • DIRECT

    • DUMP_DATE

    • EXTRACT

    • FILES

    • FILESYSTEM

    • HIST

    • LEVEL

    • PREFIX

    • RECOVER_FILEHIST

    • SINCE_TIME

    • TYPE

    • UPDATE

    • VERBOSE

    Specifying the variables above may cause unexpected results due to unpredictability of the order in which they are evaluated. NDMP servers from different vendors may support different NDMP environment variables. Except for a few well-known environment variable names, there is currently no standardized set of such variables. This option allows you to add environmental variables specific to your NDMP server.

The following fields are for Block restores only.

  • Restart Relationship After Restore Complete

    This option only takes effect when you restore an entire SnapVault filer-to-filer backup instance to its original location.

Yes

Immediately after restore, resynchronizes the restored backup instance as the most recent backup.

No

Do not resynchronize the restore. No is the default.

  • Point-in-Time Restore Fill in the Point-in-Time Restore field if you are recovering to a point-in-time other than the present. Enter the date and time (to the second) of the desired point-in-time recovery in the following format: mm/dd/yyyy hh:mm:ss The hour is based on a 24-hour clock. For example, for 11:00 p.m. on March 1, 2013, enter: 03/01/2013 23:00:00

Note. If you are recovering to the present time, be sure the Point-in-Time Restore field is empty.
