Nobody cares about data junk. Especially your personal data junk if it is all encrypted. I don't think that a lot of persons will look at your data there. If this sort of good encryption you consider for public cloud backups breaks we have a lot more problems than exposed backups.

Saying "nobody cares" about your data is not a good security policy.

[therealmarv]

hm. Security policies is something you can break with one way or another. You cannot break mathematics that way.

[cestith]

You want math? How many combinations are afforded by your "long, carefully chosen password" in a symmetric system? How many core seconds per hour does a typical botnet scriptmonger control? Cryptanalysis of GPG doesn't even matter if Eve has enough time to brute force your symmetric key.

[dillonb]

The encryption tools you are using are written by people, and can have bugs. Being careless and blindly trusting them can get you into trouble.

Who knows? Your private backups might even end up being conveniently available test data for nascent quantum decryption software.
