Any thoughts on ZFS and deduplication? Its coming in build 128 of
opensolaris and also in nexenta core 3.
It does block level, online deduplication but apparently eats up tons of RAM
and needs some CPU power.
Its a pretty interesting thought to rsync over data to a pc/hostname/date/
folder and have the filesystem dedupe. Kind of does a lot of backuppc's
logic in filesystem.
Dont know how many of you follow solaris/nexenta/ZFS but here is a fresh
The beta of nexenta core 3 can install backuppc out of box and the release
will have zfs v21 which includes online dedupe as well as 'send' dedupe so
you can mirror systems at the block level while only sending the changes.
