cannot receive incremental stream: invalid backup stream
#
I've seen this before, but have not been able to solve it....
I have copies of both streams.....
# cat backup-TBH-ZFS.sh
#!/bin/sh
DATE=`date "+%Y-%m-%d"`
DATE2=2013-03-24
#DATE2=`date -v "-1d" "+%Y-%m-%d"`
# snap the source
ssh root@tbh.lerctr.org zfs snapshot -r vault@${DATE}
# zfs copy the source to here.
ssh root@tbh.lerctr.org "zfs send -R -D -I vault@${DATE2}
vault@${DATE} | \
tee /tmp/backup.stream.send.${DATE} | \
ssh home.lerctr.org \"tee /tmp/backup.stream.receive.${DATE} | \
zfs recv -F -u -v -d zroot/backups/TBH\""
# make sure we NEVER allow the backup stuff to automount.
/sbin/zfs list -H -t filesystem -r zroot/backups/TBH| \
awk '{printf "/sbin/zfs set canmount=noauto %s\n",$1}' | sh
#
is the script I ran.
HELP.
