(generation 1).
For details about the procedures from backing up generation 1 to locking copy group 1
(generation 1), see “Locking a copy group” on page 326.
2. Use secondary volume 2 and secondary volume 3 to perform backup operation.
Use secondary volume 2 and secondary volume 3 to obtain backups for generations 2 and later.

When the copy group (generation 1) no longer needs to be locked, or to restore the contents of
secondary volume 1 to the primary volume, unlock the copy group (generation 1).
For details about how to unlock the copy group (generation 1), see “Unlocking a copy
