I edited my job (changed the start time) and QuDedup option was still greyed out.Not enabled. No change.
Maybe because I don't have any SSD's? It says that an x86 based system w SSD is recommended for Qudedup.

I formatted my USB drive a few days ago and started over. Thus the short history of past backups.
QuDedup can only be set/enabled at the initial setup of the backup job, since once the backup job has been created or run, the format of the backups would be totally different.

Yes I remembered wrong, sorry about that. Existing jobs work will still be possible to save without QuDedup.

New versioned backup jobs can't be created without QuDedup. At least I can't.
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!

Do you recommend that I create a new job (so that I can enable QuDedup) when backing up my NAS to the attached USB drive?
Isn't de-duping the content of the NAS a good thing?

I don't make any recommendations about that as the decision depend only on your situation, needs and feelings about it.

It's very good if you need deduplication (those with good control of what data they store and where often don't and then it may slow backups down) and don't mind using a proprietary backup format. Qnap offer a Win/Mac/Linux extract tool which is good. But what if a future version of those tools have a bug or don't work on the OS you prefer? What if a single bit-flip in the backup file make it unreadable? Yes you could wait 7 weeks for Qnap to analyze the issue and release a fixed extract tool but not everyone can afford to wait for that. As far as I know the backup format isn't documented so what should you do with your backup if Qnap should go out of business or maybe more likely decide to not support QuDedup any more in say 5 years?

I know that most other backup software have proprietary backup formats as well but that doesn't make it any better and I still don't like it. I've had customers come to me with their backups and asked me to restore it only to realize that the backup was unreadable. I didn't feel well about that and it was still much worse for those customers.

QuDedup is awful if you very much like the non-proprietary standard file system backup that up until now have been a trademark and excellent advantage of Qnap backup solutions. The huge benefit with a standard file system is that it is extremely easy to manage (any file management tool can be used), doesn't come with vendor lock-in, is easy to verify that the backup is restoreable, and is usually very well tried and tested by many different people not affiliated to a single manufacturer. A bit-flip usually only result in a read-error and limited damage.

My only but huge problem with QuDedup is that it's forced on the users. If it was optional (even if being the default) when using versioning I wouldn't mind. It would have been a great addition as many (probably even a majority?) of the users want backup deduplication.
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.

I confirmed that a new BU job had QuDedup selected (and greyed out, so that it could not be changed).

I did not realize that this would make the files unreadable without the Qnap's Qudedup extract tool!! I'll stay with the old defined BU job as I don't expect much space or time saving for incremental versioned backups over the USB to an attached HD. Good thing I read this thread.
