ndmpcopy disk-to-disk is normally used 3-way, for local, there is no point to use ndmpcopy. What is the problem/errors you get during 3-way ndmpcopy? > * The NDMP design doc > (http://www.opensolaris.org/os/community/arc/caselog/2007/397/) suggest there > are special capabilities for ZFS, including the ability to use snapshots and > even use 'zfs send' as opposed to 'tar' or 'dump'... but its unclear as to > whether that is done or to come. Current ndmp uses ZFS snapshot during backup: create/destroy snapshot before and after backup succeeded/aborted. Currently 'zfs send' is not used in ndmp and it's not on our roadmap. One possibility could be using ZFS send instead of tar, dump to benefit from fast block level backup. The downside is DAR and selective restores wouldnt work, but it would work for FULL dataset backup and restore. > if there is any intention to create tools (either improving ndmpcopy to do > these things or something new) for customers to utilize. No plans for improving ndmpcopy or introducing new tools at this moment. -- This message posted from opensolaris.org _______________________________________________ storage-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/storage-discuss
