Manually updating individual secondary storage system qtrees

Why to manually update a qtree on the secondary storage system

You can use the snapvault update command to manually update the SnapVault qtree on the secondary storage system from a snapshot on the primary storage system. You might want to update at an unscheduled time to protect the primary storage system data because

A disk failed on the primary storage system and you want extra protection for the data
The nightly backup failed due to a network problem
The primary storage system hardware is going to be reconfigured
You want to transfer a snapshot of a quiesced database
Note
The descriptions and procedures in this section pertain to SnapVault backup of NetApp filers only. For SnapVault backup of Opens System drives and directories, see Setting up SnapVault backup on Open Systems platforms and Managing SnapVault backup of Open Systems platforms.

How to update the snapshot on the secondary storage system

To manually update a SnapVault qtree on the secondary storage system, complete the following step.

Step	Action
1	Enter the following command from the secondary storage system: snapvault update [options] [sec_filer:]sec_qtree_path options can be one or more of the following: `-k` kbs overrides the configured rate and specifies a value in kilobytes per second for the throttle (transfer speed) for this snapshot transfer. The default value, unlimited, lets the transfer run as fast as it can. `-s` snapname enables you to specify a primary storage system snapshot that is more recent than the current base snapshot. [sec_filer:]sec_qtree_path is the name of the secondary storage system qtree that you want to update.

Step

Action

Enter the following command from the secondary storage system:

snapvault update [options] [sec_filer:]sec_qtree_path

options can be one or more of the following:

-k kbs overrides the configured rate and specifies a value in kilobytes per second for the throttle (transfer speed) for this snapshot transfer. The default value, unlimited, lets the transfer run as fast as it can.
-s snapname enables you to specify a primary storage system snapshot that is more recent than the current base snapshot.

[sec_filer:]sec_qtree_path is the name of the secondary storage system qtree that you want to update.

Example 1

filerB> snapvault update /vol/vol2/qtree3

Result

SnapVault updates the qtree on the secondary storage system (filerB) with the data from a new snapshot of the qtree it creates on the primary storage system (filerA). You do not have to specify where the primary storage system data is, because you already did so when you set up the SnapVault relationship using the snapvault start command.

Example 2

To update qtree3 on the secondary storage system (filerB) with a particular snapshot of qtree3 on the primary storage system (filerA), you would use the -s option to specify the snapshot on the primary storage system, as in the following example.

filerB> snapvault update -s my_snap filerB:/vol/vol0/qtree3

Result

SnapVault updates the qtree on the secondary storage system (filerB) with the data from a snapshot of qtree3 (my_snap) that you created earlier on the primary storage system (filerA).

Note
The snapvault update command does not create a new snapshot on the secondary storage system. Use the snapvault snap create command if you want to create a new snapshot on the secondary storage system. See Creating a snapshot manually.
