Changing settings for SnapVault backup relationships

Why you change SnapVault settings

You can use the snapvault modify command to change the primary storage system (source) qtree that you specified using the snapvault start command.

You can also use the snapvault modify command to change the SnapVault settings for transfer speed and number of tries before quitting that you entered using the snapvault start command. You might need to make these changes if there are hardware or software changes to your filers.

Note
The descriptions and procedures in this section pertain to SnapVault backup of NetApp filers only. For descriptions and procedures pertaining to SnapVault backup of Open Systems drives and directories, see Setting up SnapVault backup on Open Systems platforms and Managing SnapVault backup of Open Systems platforms.

The snapvault modify command is available only from the secondary storage system.

If you need to change the SnapVault schedule, use the snapvault snap sched command, explained in more detail in Starting a SnapVault backup relationship.

How to change SnapVault settings

To change the values you entered with the snapvault start command, complete the following step.

Step	Action
1	From the secondary storage system, enter the following command on a single line: snapvault modify [-k kbs] [-t n] [-S [prim_filer:]prim_qtree_path] [sec_filer:]sec_qtree_path `-k` kbs specifies a value in kilobytes per second for the throttle (transfer speed) for the primary storage system. A value of unlimited lets the transfer run as fast as it can. Other valid values are whole positive numbers. `-t` n specifies the number of times to try the transfer before giving up. The default is 2. Valid values are positive integers. `-S` [prim_filer:]prim_qtree_path specifies the primary storage system for the qtree. [sec_filer:]sec_qtree_path specifies the secondary storage system for the update.

Step

Action

From the secondary storage system, enter the following command on a single line:

snapvault modify [-k kbs] [-t n] 

[-S [prim_filer:]prim_qtree_path] 
[sec_filer:]sec_qtree_path

-k kbs specifies a value in kilobytes per second for the throttle (transfer speed) for the primary storage system. A value of unlimited lets the transfer run as fast as it can. Other valid values are whole positive numbers.

-t n specifies the number of times to try the transfer before giving up. The default is 2. Valid values are positive integers.

-S [prim_filer:]prim_qtree_path specifies the primary storage system for the qtree.

[sec_filer:]sec_qtree_path specifies the secondary storage system for the update.

Example

This example shows how to modify SnapVault so that it will continue backing up the data on the primary storage system filerB:/vol2/qtree3 after the name qtree3 on the primary storage system changes to qtreeBob.

filerA> snapvault status

Snapvault server is ON.

Source                    Destination                State           Lag        Status

filerB:/vol/vol2/qtree3   filerA:/vol/sv_vol/qtree3  Snapvaulted    02:48:24   Idle

[The qtree3 on filerB is renamed qtreeBob.]

filerA> snapvault modify -S filerB:/vol/vol2/qtreeBob /vol/sv_vol/qtree3

filerA> snapvault status

Snapvault server is ON.

Source                     Destination                 State          Lag       Status

filerB:/vol/vol2/qtreeBob  filerA:/vol/sv_vol/qtreeBob  Snapvaulted  0:00:31   Idle
