Hi all, I wanted to get some clarification about the following issue I am experiencing when performing a zfs send/recv: According to zfs list -r, the filesystem in question has the following sizes for it''s snapshots: obelixData/JvMpreprint 7,11T 10,2T 6,89T /obelixData/JvMpreprint obelixData/JvMpreprint at 2010-09-17_2359 5,72M - 947G - obelixData/JvMpreprint at 2010-09-18_2359 2,42M - 3,15T - obelixData/JvMpreprint at 2010-09-19_2359 21,7G - 5,24T - obelixData/JvMpreprint at 2010-09-20_2359 85,6G - 6,62T - obelixData/JvMpreprint at BackupSnapshot_2010-09-21-11 96,0M - 6,85T - obelixData/JvMpreprint at 2010-09-21_1320 422K - 6,86T - obelixData/JvMpreprint at 2010-09-21_1330 571K - 6,87T - obelixData/JvMpreprint at 2010-09-21_1340 403K - 6,87T - obelixData/JvMpreprint at 2010-09-21_1350 288K - 6,87T - obelixData/JvMpreprint at 2010-09-21_1400 256K - 6,88T - obelixData/JvMpreprint at BackupSnapshot_2010-09-21-1 354K - 6,88T - obelixData/JvMpreprint at 2010-09-21_1410 462K - 6,89T - So, now I am doing an incremental ZFS send/recv using the two "BackupSnapshots". Although the amount of data that has changed is not that big, zfs send/recv (incremental mode) blasted for approx 13 mins. at a rate of about 180 MB/s. So obviously it cannot be only the data in the snapshot that has been transferred over, since in 13 mins. at 180 MB/s this will get my a good 374 GB of data from the source to the destination. So, what is it, that gets transferred over? Cheers, budy -- This message posted from opensolaris.org
