Why is QuDedup a good idea, unless you are short of space on the backup destination?
It isn't but that's like asking why is data storage a good thing if you have no data to store?
The two biggest issues with backups that many (most?) administrators have to deal with are (probably in this order):
- Space shortage on the backup destination.
- Backups are too slow.
QuDedup, at least on paper (I haven't really used it except for a few short tests), improves the situation with both issues.
I personally don't want to use QuDedup because of the disadvantages (proprietary format, loss of administrative freedom and control) but if I had either of the previously mentioned issues (that many other administrators have) I would be a QuDedup user.
Remember that a very large majority of other backup solutions on the market have the same advantages and disadvantages. Of course it is a great feature to add for those that need it. The only (but big) problem is that Qnap made QuDedup mandatory and removed the (almost) unique feature of non-proprietary backups that they have had for many years in all their previous backup solutions.
RAID have never ever been a replacement for backups. Without backups on a different system (preferably placed at another site), you will eventually lose data!
A non-RAID configuration (including RAID 0, which isn't really RAID) with a backup on a separate media protects your data far better than any RAID-volume without backup.
All data storage consists of both the primary storage and the backups. It's your money and your data, spend the storage budget wisely or pay with your data!
