Here's what I posted the other day to zfs-discuss: So I did this: zfs send -R "rpool/export/home at bup-20090216-044512UTC" | zfs receive\ -dv "bup-ruin/fsfs" And it indicated no errors, and said it was creating various expected filesystems (pool bup-ruin was brand new at this test). And afterward bup-ruin seemed to have reasonable filesystems in it: localddb at fsfs:~/src/bup2# zfs list -r bup-ruin NAME USED AVAIL REFER MOUNTPOINT bup-ruin 35.2M 913G 23K /backups/bup-ruin bup-ruin/fsfs 35.0M 913G 18K /backups/bup-ruin/fsfs bup-ruin/fsfs/export 35.0M 913G 18K /backups/bup-ruin/fsfs/export bup-ruin/fsfs/export/home 35.0M 913G 19K /backups/bup-ruin/export/home bup-ruin/fsfs/export/home/localddb 35.0M 913G 27.8M /backups/bup-ruin/export/home/loca\ lddb localddb at fsfs:~/src/bup2# zfs list -t snapshot -r bup-ruin/fsfs/export NAME USED AVAIL REFER MOUNTPOINT bup-ruin/fsfs/export/home at bup-20090216-044512UTC 0 - 19K - bup-ruin/fsfs/export/home/localddb at first 26K - 27.6M - bup-ruin/fsfs/export/home/localddb at second 28K - 27.6M - bup-ruin/fsfs/export/home/localddb at bup-20090216-044512UTC 0 - 27.8M - And, checking a bit more deeply, the snapshot created for this backup is there, and two previous snapshots are there. Or claim to be there. But I can't actually find them anywhere. localddb at fsfs:~/src/bup2# pfexec /usr/bin/ls -a /backups/bup-ruin/fsfs/export . .. localddb at fsfs:~/src/bup2# pfexec /usr/bin/ls -a /backups/bup-ruin/fsfs/export/.zfs . .. snapshot localddb at fsfs:~/src/bup2# pfexec /usr/bin/ls -a /backups/bup-ruin/fsfs/export/.zfs/snapshot\ / . .. Note that bup-ruin is mounted with an altroot property: localddb at fsfs:~/src/bup2# zpool list NAME SIZE USED AVAIL CAP HEALTH ALTROOT bup-ruin 928G 35.3M 928G 0% ONLINE /backups/bup-ruin rpool 74G 3.85G 70.1G 5% ONLINE - zp1 744G 451G 293G 60% ONLINE - I think I need this, because the filesystems being backed up onto it have mountpoints of their own, and the originals are currently occupying those. I'm about 100.0% sure this is user error (me being the user), but I'm stuck on this right now. What am I expecting wrong?
