Fix a Backup issue possibly caused by read-only files Apps
I use Apple's Backup.app to back up files to my iDisk, and this has been working successfully for years. Recently, though, I started getting backup failures. After a lot of head scratching, it seems that Backup was failing because of a series of files that were user read-only, and had no permissions at all for group and other.

Quite why this should matter at all, I've no idea -- especially because the files get bundled into a DMG, and it's the DMG that gets uploaded to iDisk, yet it was the upload bit that was failing. Maybe keen commenters can get to the bottom of it!. Anyway, I've not done any further proofing, but suffice it to say that running the following Terminal command on the directory of files to back up solved the problem:
$ chmod -R +r .
Alternatively, you could use the Finder's Get Info window. (This is all on OS X 10.6.1, by the way.)

I hope you realize that there's no encryption when you transfer data to iDisk - it's all being transferred via plain HTTP protocol, with no encryption whatsoever. I'd think twice before using iDisk for _anything_.

Actually, there is no risk at using Backup unless one is so lazy as to expect someone else to do what they should have already done. Encrypt the DMG when you make it. That way, it's already encrypted so the fact of the DMG being transmitted without encryption is a mute issue because the DMG, itself, is encrypted. I regularly send backups to iDisk, but the files are encrypted by me and with the use of an application of my choice.....not by Apple.

Indeed. Anything sensitive would be encrypted on my Mac in the first place (key chain, encrypted DMGs).

Not that it has anything to do with the hint, of course :-)
