I've backup from my Gmail account at Outlook 2010 beta. I see a pst file which is equal file size with my Gmail used storage. I want to zip it and burn it for a yearly backup.

Is this file enough to protect my mails or do I need additional files or whatever? I'm not a regular outlook user. I've read this but I don't think I'm using "Signatures, Templates, Stationery etc."...

I don't like the idea of using pst for backup, they sometimes get corrupt with use

Short answer: it should be.

Long answer: Outlook isn't exactly the best backing storage. It works, but unfortunately, it tends to keep running in the background, which locks some of the files so they can't be backed up easily.

If you're just looking for a way to back up GMail, ie. if you aren't using Outlook for other purposes, the best solution I've found is to use a standard POP3 mailer. Thunderbird is the obvious choice, though others work, as well. There are a few good free backup utilities for Thunderbird to automate that, too.

A .pst file holds mails, only. For the mails it holds, you don't need any additional files.

When using IMAP and only keeping a yearly copy, then you're not covering the risk that somehow all your mail is lost from either Gmail or Outlook, and then after the first IMAP synchronisation (thus: as soon as you start Outlook) will be forever lost in both places.

(Hence: no, it's not sufficient to keep only a yearly backup.)
