Configuring a FlashBackup policy
Use the following procedure.
To configure a FlashBackup policy
- On the master server, open the NetBackup Administration Console.
- Click Policies.
- In the All Policies pane, right-click and select New Policy... to create a new policy.
- On the Attributes tab, select the Policy type: FlashBackup for UNIX clients, or FlashBackup-Windows for Windows clients.
FlashBackup-Windows supports the backup and restore of NTFS files that are compressed.
The files are backed up and restored as compressed files (they are not uncompressed).
- Specify the storage unit.
FlashBackup and FlashBackup-Windows policies support both tape storage units and disk storage units.
Select a snapshot method in one of the following ways:
Click Perform snapshot backups on the Attributes tab.
For a new policy, NetBackup selects a snapshot method when the backup starts.
For a copy of a policy that was configured for a snapshot method, click the Snapshot Client Options option and set the method to auto. NetBackup selects a snapshot method when the backup starts.
Click Perform snapshot backups, click the Snapshot Client Options option and select a snapshot method.
- Windows only: to enable the backup for Instant Recovery, select Retain snapshots for Instant Recovery or SLP management.
Instant Recovery is not supported for FlashBackup with UNIX clients.
UNIX only: if you selected nbu_snap or VxFS_Snapshot as the snapshot method, specify a raw partition as cache, in either of these ways:
Use the Host Properties node of the Administration Console to specify the default cache device path for snapshots. Click Host Properties > Clients, select the client, then Actions > Properties, UNIX Client > Client Settings.
Use the Snapshot Client Options dialog to specify the cache.
See Entering the cache.
The partition to be used for the cache must exist on all clients that are included in the policy.
- To shift backup I/O to an alternate client, or to a NetBackup media server or third-party copy device (UNIX clients only), select Perform off-host backup.
For FlashBackup, the Use data mover option is supported for UNIX clients only.
- To reduce backup time when more than one raw partition is specified in the Backup Selections list, select Allow multiple data streams.
- Use the Schedules tab to create a schedule.
FlashBackup policies support full and incremental types only. User backup and archive schedule types are not supported.
A full FlashBackup backs up the entire disk or raw partition that was selected in the Backup Selections tab (see next step). An incremental backup backs up individual files that have changed since their last full backup, and also backs up their parent directories. The incremental backup does not back up files in parent directories unless the files have changed since the last full backup.
For incremental backups, a file is considered "changed" if its Modified Time or Create Time value was changed.
Note on FlashBackup-Windows: The NTFS Master File Table does not update the Create Time or Modified Time of a file or folder when the following changes are made:
Changes to file name or directory name.
Changes to file or directory security.
Changes to file or directory attributes (read only, hidden, system, archive bit).
- On the Backup Selections tab, specify the drive letter or mounted volume (Windows) or the raw disk partition (UNIX) containing the files to back up.
For Windows
Windows examples
\\.\E: \\.\E:\mounted_volume\
where:
\\.\E:is a Windows disk volume mounted on a drive letter.
\\.\E:\mounted_volume\ (note the trailing backslash) is a Windows disk volume without a drive letter mounted on a directory (Windows reparse point).
The drive must be designated exactly as shown (E:\ is not correct). Backing up the drive containing the Windows system files (usually the C drive) is not supported.
Solaris examples
/dev/rdsk/c1t0d0s6 /dev/vx/rdsk/volgrp1/vol1
HP examples
/dev/rdsk/c1t0d0 /dev/vx/rdsk/volgrp1/vol1
For UNIX
The Backup Selections tab must specify the raw (character) device corresponding to the block device over which the file system is mounted. For example, to back up /usr, mounted on /dev/dsk/c1t0d0s6, enter raw device /dev/rdsk/c1t0d0s6. Note the r in /rdsk.
Note:
Wildcards (such as/dev/rdsk/c0*) are not permitted. Specifying the actual device file name such as /devices/pci@1f,0/pci@1/scsi@3/sd@1,0:d,rawis not supported.
Note:
Wildcards (such as/dev/rdsk/c0*) are not permitted. Specifying the actual device file name such as /devices/pci@1f,0/pci@1/scsi@3/sd@1,0:d,rawis not supported.
- Use the Clients tab to select clients to back up.
Each client in the client list must contain all the raw partitions that are specified in the Backup Selections tab. Exclude and include lists cannot be used to circumvent this requirement.
- On the policy Attributes tab: if you click Apply or OK, a validation process checks the policy and reports any errors. If you click Close, no validation is performed.
