The closest thing I can find is:
http://bugs.opensolaris.org/view_bug.do?bug_id=6421958
But just like it says: " Incremental +
recursive will be a bit tricker, because how do you specify the multiple
source and dest snaps? "
Let me clarify this more:
Without "send -r" I need do something like this;
Given a zfs file system "myzfs" in zpool "mypool", it has N snapshots:
mypool/myzfs
mypool/[EMAIL PROTECTED]
mypool/[EMAIL PROTECTED]
....
mypool/[EMAIL PROTECTED],
Do following things:
zfs snapshot mypool/[EMAIL PROTECTED]
zfs send mypool/[EMAIL PROTECTED] | gzip - > /somewhere/myzfs-current.gz
zfs send -i mypool/[EMAIL PROTECTED] mypool/[EMAIL PROTECTED] | gzip - >
/somewhere/myzfs-1.gz
zfs send -i mypool/[EMAIL PROTECTED] mypool/[EMAIL PROTECTED] | gzip - >
/somewhere/myzfs-2.gz
......
zfs send -i mypool/[EMAIL PROTECTED] mypool/[EMAIL PROTECTED] | gzip - >
/somewhere/myzfs-N.gz
As you can see, above commands are kind of a stupid solution, and it
didn't reach maximum efficiency because those "myzfs-<1 ~ N>.gz" files contain
a lot of common stuffs in them!
I wonder how will "send -r" do in above situation? How does it choose
multiple source and dest snaps? And can "-r" efficient enough to just dump the
incremental changes? What is the corresponding receive command for "send -r"?
(receive -r ? I guess? )
Thanks!
