Hi, I''m trying to do a simple data retention hack wherein I keep hourly, daily, weekly and monthly zfs auto snapshots. To save space, I want the dailies to go away when the weekly is taken. I want the weeklies to go away when the monthly is taken. From what I''ve gathered, it seems time slider just deletes the eldest snapshot when there''s space contention.

This may be a bit poorly thought through but in this case I don''t really know enough to really think it through. My back ground is linux... there I used a tool called rsnapshot which used rsync and some hardlink magic to create versioned backups. But take very little space. By versioned I don''t mean as in version control but just copies of files as they change. It worked by

...plicate a 300 GB pool with this command zfs send alpha at 3 | zfs receive -F omega about 2 hours in to the process it fails with this error "cannot receive new filesystem stream: invalid backup stream" I have tried setting the target read only (zfs set readonly=on omega) also disable Timeslider thinking it might have something to do with it. What could be causing the error ? if the target is a new hard drive can I use this zfs send alpha at 3 > /dev/c10t0d0 ? Thanks -- This message posted from opensolaris.org

Hi, I have an idea about improvements of ZFS from the one side and improvements for of the GUI interface from the other side. Let me describe my idea. >From the one side we have an ZFS on-th-fly snapshots, and starting from OpenSolaris 2008.11 we have TimeSlider user feature based on ZFS snaphots. So, we made a big step to the user. But from the other side we still have in GUI interface "old" Move-To-Trash behaviour: this is usual mv command when user delete files on he''s ZFS partition and copy+delete commands for all other partitions....
