Changing settings for SnapVault backup relationships

You can change the values you entered with the snapvault start command.

Step

1. From the secondary storage system, enter the following command on a single line: snapvault modify [-k kbs] [-t n] [-o options] [-S [prim_system:]prim_qtree_path] [sec_system:]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.

   If set to 0, the secondary storage system does not update the qtree. This is one way to temporarily stop updates to a qtree.

   options is opt_name=opt_value [[, opt_name=opt_value ]...]. For more details about the available options, see the SnapVault man page.

   Note: To ensure that SnapVault does not transfer inodes because of access time changes when a client reads a file, set -o ignore_atime=on.

   -S [prim_system:]prim_qtree_path specifies the primary storage system for the qtree. [sec_system:]sec_qtree_path specifies the secondary storage system for the update.
