Backing up has nothing whatsoever to do with being able to use it on some future device you might own in 10 years time. It really doesn't help anyone to try to conflate these two entirely separate topics.

Sorry if I add to this off-topic...
I think your misunderstanding come for the use of verbs. Actually, IT people like me, use the verb "to back up" meaning the whole backup and restore process.
You're right, DRM does not prevent backup, it just makes DATA restore almost impossibile, which makes the first half of the process completely pointless.
Remeber: the point of backup is not to recover files, it's to recover the data in them! (Most of the commercial backup solutions store data in a different file format than the original one...)
So you're both right.
DRM prevents backup, if you mean the whole data backup/copy/restore thing.
DRM does not prevent backup, just data restore (*), if you're very precise in your choice of words.
DRM does not prevent backup nor restore of the zeros and ones which constitute your file, if you're nitpicking in your vocabulary and splitting the hair in two just to not concede a point.

(*) Actually, restore of DRM'd data is possibile, albeit only in the very unlikely scenario in which you restore your data on the very same device the backup came from.
