I''m trying to do a simple backup.

This is probably 6696858. The fix is known, but I don''t know when it''s expected to become available. I have asked the CR''s responsible engineer to update it with when the fix is expected.

I''d like to maintain a backup of the main pool on an external drive. Can you suggest a way to do that? I was hoping to do zfs send | zfs receive and then do that with incrementals. It seems that this isn''t going to work. How do people actually back up ZFS-based systems? -- This message posted from opensolaris.org
