Brian,

Can you test it and confirm it it works or not?

Jean-Louis,

This will create two snapshot of /export/home, if they include the subdirs, then it should works.

It must be tried.

but if the snapshots have the same name, /export/home-amanda current,
then the second, 3rd... will fail. I have to wonder what happens to
uncompleted dumps when the first dump completes and attempts to destroy
the snapshot.

I've been away (10-days in Germany) and I no longer recall if
I was afraid of leaving as largely untested globing config behind.

I left it with dumptype user-tar rather than zfs-snapshot and we
have been successfull.

I have to note however that the zfs manager is running a nightly
snapshot of the zfs mount points each day. A 5/weekly recursive
snapshot of the pool, where each new "monday" snapshot destroyes
the old and creates a new one. We still have snapshots, but not
through amanda. I believe the idea was to allow user directed
file recovery, since old files will remain available for 7 days.

I may give this (zfs-snapshot) a try in this config now that I
am back. If so I will let you know the result. Dangerous to assume
I've tested and not resported.

                                                thank you,

                                                Brian

Using amanda 2.6.1 on Solaris 10 (server x86, client Sparc)

I currently have entries in the disklist like these, currently
there are 55+ entries.

finsen  /export/home/agaupel    zfs-snapshot
finsen  /export/home/along      zfs-snapshot
finsen  /export/home/amanda     zfs-snapshot
finsen  /export/home/bhowland   zfs-snapshot
finsen  /export/home/brainard   zfs-snapshot
finsen  /export/home/cbryant    zfs-snapshot
finsen  /export/home/cchen      zfs-snapshot
finsen  /export/home/dkim       zfs-snapshot
finsen  /export/home/dmuller    zfs-snapshot

Each user directory is its own zfs mount point.

Can I successfully replace them with entries like this ?

I think this will do what I think it does, because I do it
on other machines, but the zfs-snapshot is a new addition
to this structure.

finsen  /export/home-A /export/home  {
       zfs-snapshot
       include "./[a]*"
       }

finsen  /export/home-B /export/home  {
       zfs-snapshot
       include "./[b]*"
       }

This will create two snapshot of /export/home, if they include the subdirs, then it should works.

It must be tried.
