Re: [zfs-discuss] ZFS

i do send the tapes offline. The idea of sending onto another system seems an excellent idea but i would still need to send them to tape. if i tar or dump the replicated filesystems this will chew up a lot of space since my filesystems are almost 900GB in total On Tue, Sep 13, 2011 at 11:07 AM, Ia

Concerning native Solaris tools: Solaris tar takes a 'p' flag that stores ACL information, and re-creates same when extracted. I've not made much use of it yet, but it apparently works on UFS and ZFS (although there are obvious difficulties restoring ZFS ACLs to UFS, etc.) Gtar on Linux extract
