I wonder if there are any equivalent commands in zfs to dump all its associated
snapshots at maximum efficiency (only the changed data blocks among all
snapshots)? I know you can just "zfs send" all snapshots but each one is like
a full dump and if you use "zfs send -i" it is hard to maintain the
relationship of the snapshots.
In NetApp filer, I can do "snapmirror store /vol/vol01 ..." then everything
in /vol/vol01 and all of its snapshots will be mirrored to destination, and it
is block level which means only the changes in snapshots are sent out.
So I wonder if there is an equivalent for ZFS to do similar things:
For example: given one zfs: diskpool/myzfs, it has n snapshots:
diskpool/[EMAIL PROTECTED], diskpool/[EMAIL PROTECTED],......
diskpool/[EMAIL PROTECTED],
and if you just do "zfs < magic subcommands> diskpool/myzfs ..." and it will
dump myzfs and all its n snapshots out at maximum efficiency (only changed data
in snapshots) ?
Any hints/helps are aprreciated!
