Thanks for your comments! I think I roughly understand the feature trade-offs, and have some experience with back-up solutions ranging from simple to enterprise. I guess what I am after is, for data which really matters to its owners and which they actually had to recover, did people use tar/pax archives (~ file level standard archive format), dump/restore (~ semi-standard format based on files/inodes) or zfs send/receive (~ file system block level dump), or something else, and why? (Regardless of how these are implemented, hobby scripts or enterprise tools, how they dealt with possible media failure issues, etc.) Other than the file system vs. file restore, is there any concern in doing the block level thing? "Concerns" as in "mind being in the line of fire if it fails?" :-) Regards, Lassi _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
