Hi
maybe use snapshot volume (i scalix runs on linux)
ClientRunBeforeJob
scalix stop
create snapshot volume of your scalix filesystem volume
scalix start
mount snapshot readonly
Job
Backup snapshot mount point
ClientRunAfterJob
unmount shapshot
remove snapshot volume
There is only a short downtime for scalix.
I'v setup this for a full linux system which includes
a 10G mysql database, but i dont shutdown or dump the
database (just flush an lock tables while snapshot is
created). I runs without problems for weeks.
A nice FileSet option is "strippath=1", so you
can restore the snapshot to its original location.
