Clonebox is fine for home use...it's not enterprise grade though, please don't represent that it is to the droves of slashdot readers.
This is why Clonebox and similar solutions are not "enterprise grade":
1) no deduplication
2) no media lifecycle management
3) no encryption keys that you control
4) you do not control *where* the data lives
You said "enterprise grade" - reason #4 alone clobbers that assertion.
If you want to get "enterprise grade", please consider backup systems aimed at, well, *enterprises*.
Some examples for you:
1) Bacula (open source, requires an IQ above a demented bee to admin)
2) Symantec Netbackup (expensive, IQ required)
3) Commvault (expensive, minimal IQ required)
Clonebox may work *great* for you and your business - by all means keep using it! Nothing wrong with plugging it either, but please don't plug it as "enterprise grade". Somewhere some new-hire slashdotter may take that as gospel and cost him or herself their job in the future - or at the very least look like foolish in front of their peers when they parrot it.
