I use SkyDrive the same way others here use Dropbox. Meaning, I keep my Calibre library in my SkyDrive folder, which is automatically uploaded to the cloud. I also run both Calibre and SkyDrive on two separate computers, so I always have two local copies of my library in addition to the cloud.

Oh, and I keep my entire library on my Kindle, so that's another copy.

In terms of maintenance for the books themselves, these are the steps I go through whenever I buy a new book:

1. Add it to Calibre, which automatically removes the DRM when necessary.

2. Change the cover when necessary. With backlist books there's often a lot of different covers out there, and I want each book in Calibre to have the same cover as my paper book did. And if I've never owned the title in the past, I just make sure it's a cover with good resolution and with no borders.

3. Make sure some metadata fields have the right info in them:
a) Title, Author, Series, Publisher, Language (self explanatory)
b) Published (when the title was originally published, not when the current edition was published)
c) Comments (just an overview of the book and nothing else, sometimes this is downloaded using Calibre, sometimes sourced from Amazon or Wikipedia)
d) Tags (I only use three tags: Fiction, Non-Fiction, Manuals & Reference)
e) Custom metadata: Store bought from, Price paid (self explanatory)

4. And finally, when necessary I convert the book to mobi

The only other thing I do is track when I start and finish books. I do this via two custom metadata fields.
