G'day, I'm putting together a LAN server with a couple of terabyte HDDs as a mirror (zfs root) on b117 (updated 2009.06).
I want to back up snapshots of all of rpool to a removable drive on a USB port - simple & cheap backup media for a two week rolling DR solution - ie: once a week a HDD gets swapped out and kept offsite. I figure ZFS snapshots are perfect for local backups of files, it's only DR that we need the offsite backup for. I created and formatted one drive on the USB interface (hopefully this will cope with drives being swapped in and out?), called it 'backup' to confuse things :) zfs list shows : NAME USED AVAIL REFER MOUNTPOINT backup 114K 913G 21K /backup rpool 16.1G 897G 84K /rpool rpool/ROOT 13.7G 897G 19K legacy rpool/ROOT/opensolaris 37.7M 897G 5.02G / rpool/ROOT/opensolaris-1 13.7G 897G 10.9G / rpool/cashmore 140K 897G 22K /rpool/cashmore rpool/dump 1018M 897G 1018M - rpool/export 270M 897G 23K /export rpool/export/home 270M 897G 736K /export/home rpool/export/home/carl 267M 897G 166M /export/home/carl rpool/swap 1.09G 898G 101M - I've tried this : zfs snapshot -r rp...@yyyymmddhh zfs send rp...@yyyymmddhh | zfs receive -F backup/data eg : c...@lan2:/backup# zfs snapshot -r rp...@2009070804 c...@lan2:/backup# zfs send rp...@2009070804 | zfs receive -F backup/data Now I'd expect to see the drive light up and to see some activity, but not much seems to happen. zpool status shows : # zpool status pool: backup state: ONLINE scrub: none requested config: NAME STATE READ WRITE CKSUM backup ONLINE 0 0 0 c10t0d0s0 ONLINE 0 0 0 errors: No known data errors pool: rpool state: ONLINE scrub: none requested config: NAME STATE READ WRITE CKSUM rpool ONLINE 0 0 0 mirror ONLINE 0 0 0 c8d1s0 ONLINE 0 0 0 c9d1s0 ONLINE 0 0 0 errors: No known data errors and zfs list -t all : zfs list -t all | grep back backup 238K 913G 23K /backup bac...@zfs-auto-snap:frequent-2009-07-08-23:30 18K - 21K - backup/data 84K 913G 84K /backup/data backup/d...@2009070804 0 - 84K - So nothing much is getting copied onto the USB drive as far as I can tell. Certainly not a few GB of stuff. Can anyone tell me what I've missed or misunderstood? Does snapshot -r not get all of rpool? Thankyou!
