FlashBackup restrictions
Note the following restrictions:
FlashBackup policies do not support file systems that HSM manages.
FlashBackup policies for UNIX clients do not support Instant Recovery.
FlashBackup does not support VxFS storage checkpoints that the VxFS_Checkpoint snapshot method uses.
FlashBackup supports the following I/O system components: ufs, VxFS, and Windows NTFS file systems, VxVM volumes and LVM volumes, and raw disks. Other components (such as non-Veritas storage replicators or other non-Veritas volume managers) are not supported.
FlashBackup on Linux supports only the VxFS file system on VxVM volumes. For Linux clients, no other file system is supported, and VxFS file systems are not supported without VxVM volumes.
FlashBackup on AIX supports only the VxFS file system, with VxVM or LVM volumes. For AIX clients, no other file system is supported, and the data must be over a VxVM or LVM volume.
Note these restrictions for Windows clients:
The use of FlashBackup in a Windows Server Failover Clustering (WSFC) environment is supported, with the following limitation: Raw partition restores can only be performed when the disk being restored is placed in extended maintenance mode or removed from the WSFC resource group.
FlashBackup-Windows and Linux policies do not support a Client Direct restore.
FlashBackup-Windows policies support Instant Recovery, but only for backup to a storage unit (not for snapshot-only backups).
FlashBackup-Windows policies do not support the backup of Windows system-protected files (the System State, such as the Registry and Active Directory).
FlashBackup-Windows policies do not support the backup of Windows OS partitions that contain the Windows system files (usually C:).
FlashBackup-Windows policies do not support the backup of Windows System database files (such as RSM Database and Terminal Services Database).
FlashBackup-Windows policies do not support "include" lists (exceptions to client "exclude" lists).
A restore from a FlashBackup-Windows image will not work if the destination client is not a Windows host.
FlashBackup-Windows supports the backup and restore of NTFS files that are compressed. FlashBackup-Windows does support Windows NTFS encryption and compression, but not NetBackup's compression or encryption.
Note:
The compressed NTFS files are backed up and restored as compressed files (they are not uncompressed).
FlashBackup (UNIX) does not support any type of compression or encryption, whether the encryption/compression is set in the NetBackup policy or in the Operating System.
