Table: Snapshot method descriptions
NetBackup selects a snapshot method when the backup starts. If necessary, NetBackup selects a different method for each item in thelist.
For mirror snapshots on alternate clients, with the VxVM FlashSnap feature. This method is for clients on Solaris, HP, AIX, Linux, and Windows. UNIX clients must be at VxVM 3.2 or later. Linux and AIX clients must be at VxVM 4.0 or later. Windows clients must be at VxVM 3.1 or later, with all the latest VxVM service packs and updates.
FlashSnap is based on the VxVM disk group split and join technology.
For snapshots of Hyper-V virtual machines.
Refer to the NetBackup for Hyper-V Administrator's Guide:
For copy-on-write snapshots of client data that resides on an NDMP host. Requires NetBackup for NDMP software. Further information is available on requirements and configuration details.
NetBackup does not currently support extended volume table of contents (VTOCs) or EFI labels when nbu_snap is used with the UNIX file system (UFS). NetBackup supports an effective limit of 1TB disks (regardless of partition size) when UFS and nbu_snap are used together. To use nbu_snap with a larger disk (greater than 1TB), you must use VxVM instead of UFS.
This method requires a raw partition that is designated for cache.
For snapshots of VMware virtual machines.
Refer to the NetBackup for VMware Administrator's guide
VSS uses the Volume Shadow Copy Service of Windows and supports Instant Recovery. VSS is for local backup or alternate client backup.
For the most up-to-date list of Windows operating systems and disk arrays supported by this method, see the following NetBackup Snapshot Client Configuration document:
For alternate client backup, the client data must reside on: either a disk array such as EMC, HP, or Hitachi with snapshot capability, or a Veritas Storage Foundation for Windows 4.1 or later volume with snapshots enabled. VSS supports file system backup of a disk partition (such as E:\) and backup of databases.
VSS-based snapshot methods offer a general interface to Windows Shadow Copy Services. VSS selects the actual snapshot method depending on which snapshot provider is configured on the client. For instance, if the data resides on an EMC CLARiiON array, and the array administrator configured the array and its snapshot capability: the Volume Shadow Copy Service selects the appropriate CLARiiON VSS hardware provider to take the snapshot.
For alternate client backups of a replicated VxVM volume. For clients on Solaris, HP, Linux, AIX.
Requires VxVM 3.2 or later with the Veritas Volume Replicator license. Linux and AIX clients require VxVM 4.0 or later.
For copy-on-write snapshots of clients on Solaris, HP, AIX, or Linux. The FlashBackup policy type does not support this method.
Requires the Storage Checkpoint feature of VxFS 3.4 or later. HP requires VxFS 3.5 or later. Linux and AIX clients require VxFS 4.0 or later.
Note that VxFS_Checkpoint requires the Snapshot Client license and the Veritas File System license with the Storage Checkpoints feature. Without both licenses, the copy-on-write snapshot (Storage Checkpoint) cannot be opened and the backup fails.
For copy-on-write snapshots of Solaris or HP clients on the local network (not off-host), for FlashBackup policies only. This method requires VxFS 3.4 (Solaris) or VxFS 3.3.2 (HP) or later. This method also requires a designated cache.
Note that all files in thelist must reside in the same file system.
For any of the following types of snapshots with data configured over Volume Manager volumes, for clients on Solaris, HP, AIX, Linux, or Windows. Linux and AIX clients require VxVM 4.0 or later.
Creates asnapshot (copy-on-write) of database backup shares on the NetBackup appliance.
