Hi Sven, all,

In 3.3 there is a new utility called engine-backup.

Documentation is currently somewhat lacking.

'engine-backup --help' will tell you its options.

As Eli implied below, there is no need to take down the engine/jboss
services while backing up.

Restore should be done to an empty database.

Some improvements for it were merged in recently, some of them will
be included in 3.3.1.
