Because ZFS is a relatively new file system, not all the giant corporate and well known backup/restore tools are able to support it. It is the case by now using EMC NetWorker and Veritas NetBackup. Not before the first half of the next year for TSM, IBM support said.
So. In order to backup ZFS file system with this tool, we need to write a little script which will launch the TSM CLI utility, thus backup'ing the wanted ZFS file systems. (This hack does not support the new ZFS ACLs, though.)
Here it is:
# grep postschedulecmd /opt/tivoli/tsm/client/ba/bin/dsm.sys
postschedulecmd "/root/bin/tsm.do.post.sh >> \
/opt/tivoli/tsm/client/ba/bin/dsmsched.log 2>&1"
#
# cat /root/bin/tsm.do.post.sh
#!/usr/bin/env sh
PATH=/usr/sbin:${PATH}
export PATH
for mount in `zfs mount | awk '$0 ~ /.*\/.*\/.*/ {print $2}'`; do
dsmc i ${mount} -subdir=yes
done
exit 0
Just relaunch the TSM scheduler, and watch your dsmsched.log log file
with care.
