Best Free Email Backup Utility



For many people, email backup is nearly as—or more—important than backing up documents. Yet it's often not as easy. And if you have more than one account, backup can quickly get out of hand, particularly if you need to find some particular message(s).

  • offers cloud-based backup for most email services. It is a new service, just getting started - March 1, 2012. It has a well developed website and cloud interface, and is easy to set up for your account. The free account offers only 120 MB of storage, but you can expand that by getting your friends to sign up too (5 GB is $9.99 per year).

  • Thunderbird can be used to back up any accounts that offer POP or IMAP access. Just add the accounts you want to back up, and then run Thunderbird when you want to create/update a backup. Of course Thunderbird saves server settings, but contacts are not included. You need to import them directly to Thunderbird from each of your email clients or accounts, or back them up separately.

  • Comodo Backup is a general purpose backup utility, which also backs up email. It also offers 5 GB of online storage. Comodo works by backing up email that has already been downloaded by clients. It supports Thunderbird, Eudora, Microsoft Outlook 2003, Microsoft Outlook 2007, Windows Live Mail and Outlook Express. You can back up server settings, but evidently not contacts. It also backs up any files you select.

  • MailBrowserBackup is a simple standalone (no install) program that detects and offers to back up Internet Explorer (Favorities ONLY), Mozilla Firefox (profile), Flock, Windows Mail, Windows Contacts (Win 7), Windows Live Mail, Mozilla Thunderbird, Opera (browser & mail), Apple Safari, Google Chrome, SRWare Iron, FileZilla FTP Client and Windows Live Messenger Plus.

    In Windows 7 I found that you must be running as an Administrator in your own account or MailBrowserBackup will not back up Windows Contacts for your own account. You can open the backup archives with 7-Zip (and maybe other programs) and see exactly what's in them. Of course you could also extract them with 7-Zip.

  • Microsoft has a free backup program for Outlook that creates backup copies of your .PST files at regular intervals. For Outlook 2002 and later versions.

Great way to carry all your emails with you.
Just set up MailStore Portable with my Thunderbird email. Took a few tries which I blame on Tbird but really great program. Good instructions on website. I also use MozBackup but that doesn't allow me to view the emails like MailStore.

About MailStore Home, i'm not used to having to download the installer to get the portable version, when it's available from the developer. It's usually an archive. It took a while of looking for the portable version before i read in the installation that it was in the installer.

btw the installer tried to call home.

No scheduler, not enough compression, i'll just keep using a backup program to make a compressed backup of my Thunderbird portable's Mail directory.
