In particular, might you be using the -d and -F options, or more precisely, failing to do so? They're useful for keeping your snapshots in sync between source and backup, though it's been so long since I setup my backups that I no longer recall exactly how things break if you leave them off. See the examples in the man page. I can tell you, however, that with zxfer -vFdk -o setuid=3Doff,compression=3Dlz4 -T mirrors@filer.radel.com = -R zroot pool1/mirrors/stream.radel.com I do *not* see the problem you describe and routinely have the zxfer kicked off by cron once an hour "catch up" on multiple new snapshots created while my backup server was not doing all it should. --=20 --Jon Radel jon@radel.com
