Managing SnapVault backup of Open Systems platforms
Central management of Open Systems SnapVault agents
Open Systems SnapVault agents for all operating systems can be centrally managed using one of the following management tools:
Where to find status and problem reports
You can find primary storage system operational status and problem reports in a log file called snapvault. The snapvault log file is located in the following directory:
install_dir/snapvault/etc
install_dir is the directory on the primary storage system in which you installed the Open Systems SnapVault agent. On Windows systems, the default location for install_dir is the c:\Program Files directory. On UNIX systems, the default location for install_dir is the /usr directory.
You can find secondary storage system reports in the /etc/log/snapmirror file in the root volume.
What SnapVault operations are possible on Open Systems platforms
SnapVault backup and restore of an Open Systems platform is carried out using many of the same commands that are used to manage backup and restore of primary storage systems.
In many cases, the required input for a command is different, reflecting the fact that Open Systems platforms are not organized in qtrees. Instead of primary qtrees, the user specifies directories or volumes to be backed up from the Open Systems platform.
Where directories and volumes are backed up
Each directory or volume you want backed up from a primary storage system is backed up to its own qtree on the SnapVault secondary storage system.
Secondary side SnapVault commands applied to Open Systems platforms
The following SnapVault commands can be entered at the command line of the SnapVault secondary storage system.
Command
|
Input for Open Systems platforms
|
|---|
license add
|
Specifies the license information for the SnapVault
secondary storage and primary storage systems.
Syntax
At the secondary storage console, enter
license add license_no
|
options
snapvault.enable
|
Enables SnapVault on the secondary storage system.
Syntax
At the secondary storage console, enter
options snapvault.enable {on|off}
|
options
snapvault.access
|
Specifies the platforms that can be backed up by
SnapVault.
Syntax
At the secondary storage console, enter
options snapvault.access
host=prim_host[,prim_host...]
|
snapvault start
|
Starts the initial backup of data from the Open Systems platform volumes and directories to SnapVault secondary storage qtrees.
Syntax
At the secondary storage console, enter
snapvault start -S prim_host:dirpath
sec_host:vol/sec_vol/sec_tree
Example 1 (Windows)
snapvault start -S winservrB:c:\documents
sv_hostA:vol/sv_vol/documents
Example 2 (UNIX)
snapvault start -S uxservrB:/usr/documents
sv_hostA:vol/sv_vol/documents
|
snapvault snap
sched -x
|
Schedules sets of incremental backups to all secondary system qtrees on a specified volume from their primary directory sources on Open Systems platforms.
After each incremental backup, SnapVault then creates a Snapshot copy of updated secondary system qtrees for long-term storage.
Syntax
At the secondary storage console, enter
snapvault snap sched -x volume_name snap_name
count@weekday-weekday@hour
Example
snapvault snap sched -x sv_vol sv_daily
5@Monday-Friday@23
|
snapvault update
|
Carries out unscheduled incremental SnapVault backups from Open Systems platform drives or directories to the secondary storage qtree.
Syntax
At the secondary storage console, enter
snapvault update [-k kbs] [-s snapname]
[sec_host:]sec_qtree_path
|
snapvault modify
|
Modifies a SnapVault relationship.
Syntax
At the secondary storage console, enter
snapvault modify [-k kbs] [-t n]
[-S [prim_host:][dir_path]
[sec_host:]/vol/sec_vol/sec_qtree_path
|
snapvault abort
|
Stops an ongoing transfer of data (scheduled by the snapvault snap sched -x command or invoked by the snapvault start or snapvault update commands) from an Open Systems platform source to a specified secondary system qtree.
Syntax
At the secondary console, enter
snapvault abort [sec_system:] sec_qtree_path
|
snapvault stop
|
Ends a SnapVault relationship between a secondary system qtree and its Open Systems platform source.
Syntax
At the secondary console, enter
snapvault stop [sec_system:] sec_qtree_path
|
snapvault snap
unsched
|
Unschedules a set of incremental backups to the secondary system qtrees on a specified volume. This set of incremental backups was originally scheduled through the snapvault snap sched command. This command does not end the SnapVault relationships between the secondary system qtrees and their Open Systems platform source drives or directories.
Syntax
At the secondary storage console, enter
snapvault snap unsched [volume_name]
[snap_name]
Example
snapvault snap unsched sv_vol sv_daily
|
snapvault
restore
|
Restores a directory, subdirectory, or file from the secondary system to the Open System platform.
Syntax
At the Open System platform console, enter
snapvault restore -S
[sec_system:]sec_qtree_path prim_qtree_path
|
