Snapshotproviderimage

Use the snapshotproviderimage option to enable snapshot-based image backup, and to specify a snapshot provider.

Linux operating systems AIX operating systems You must be a root user to perform a snapshot-based image backup operation. If you are not a root user, the operation fails with an error message.

Supported Clients

Linux operating systems AIX operating systems This option is valid for AIX® and Linux® clients only. The IBM® Storage Protect API does not support this option. The server can also define this option.

Windows operating systems This option is valid for all Windows clients. The IBM Storage Protect API does not support this option. The server can also define this option.

Options File

Linux operating systems AIX operating systems Specify this option in the server stanza of the system-options file, dsm.sys, to enable snapshots for all the file systems on the client. You can override the client-wide option for a specific operation by specifying this option on the command line for the backup image command. You can also override the client-wide option for a specific file system using the include.image statement in the dsm.sys file. You can also set this option using the Preferences editor.

Windows operating systems Specify this option in the client options file, dsm.opt, to enable snapshots for all the file systems on the client. You can override the client-wide option for a specific operation by specifying this option on the command line for the backup image command. You can also override the client-wide option for a specific file system using the include.image statement in the dsm.opt file. You can also set this option using the Preferences editor.

Syntax

Parameters

value: Specifies one of the following values:
JFS2: Specifies that you want to perform a snapshot-based image backup while the file system is available to other system applications. This is the default for JFS2 file systems. Valid for AIX clients only.
LINUX_LVM: Specifies that you want to perform a snapshot-based image backup while the file system is available to other system applications. This is the default for file systems residing on logical volumes created by the Linux Logical Volume Manager. Valid for Linux clients only.
VSS: Specifies that VSS should be used to provide OFS support. This is the default.

Note: Starting from IBM Storage Protect 8.1.8, the default value for SNAPSHOTPROVIDERFS and SNAPSHOTPROVIDERIMAGE has been changed from NONE to VSS. This change makes the best practice behavior the default behavior.
NONE: Specifies that you do not want to perform a snapshot-based image backup operation. This performs a static image backup operation using the specified file system. This is the default for file systems other than AIX JFS2 and Linux LVM.
NONE: Specifies that no snapshot provider should be used. This turns off online image support.
