For many years I have used Retrospect for backing up our home computers. It's very important to have a thought-through backup strategy, that includes keeping more than one copy of your data, including at least one copy that is "off-site". If disaster strikes, such as your computer hard-drive failing, you wouldn't want to lose all your documents, photos and possibly emails.
Our church produces a quarterly magazine that goes, free, to every household in our parish. It's called The Well.
As vicar, I get to write a letter near the front of each issue, in which I seek briefly to bring a Christian perspective to bear on some contemporary issue or other.
