Review: Mirra Personal Server: Page 2 of 4

Mirra scanned my selected folders and began the process of copying my files to its drive. It successfully copied not only all the files in the My Documents folder, but also my Outlook file while Outlook was running. Mirra is able to perform this magic on Windows XP and 2003 Server, but not on Windows 2000, because it relies on Microsoft's Shadow Copy feature to save copies of active files. Shadow Copy is included in only the most recent versions of the Windows OS, which is why Mirra doesn't support older versions of Windows.

That Syncing Feeling
Once you've made a backup of your files, you can elect to share some or all of them either with users on your LAN or with remote users over the Internet. If you choose to share your files with PCs connected to your LAN, the files you share will be kept up to date. Mirra's client software constantly monitors the files you select for backup. Every time you save a file, Mirra stores it along with the seven previous versions on the Mirra server, then distributes the most recent copy to all PCs that have been selected to have copies.

This trick has been tried by many different software products, but I've always found some kind of "gotcha" in the implementation. I installed the Mirra client on my Toshiba M35 laptop and selected the same My Documents folder and the Outlook.pst file I had backed up from my desktop PC. Once my folders were copied from the Mirra to my laptop, I fired up Outlook, opened the Outlook.pst file that was being shared, and saw the same e-mail messages I had just received on my desktop.

Mirra is not Microsoft Exchange Server and isn't intended to support multiple simultaneous users of the same file. So, to check to see if the updates actually worked, I closed Outlook on my desktop machine and deleted an e-mail from the laptop Outlook session. I then closed Outlook on the laptop and opened it on my desktop, and the message was in fact deleted.

This is a huge step forward for those of us using two (or more) computers and needing the same information on all of them. The advantage is you no longer have to find a way to get your appointments, contacts, and e-mail from your desktop to your laptop every time you walk out the door with your laptop. (Just make sure you shut down your desktop PC -- or at least Outlook -- before you leave the office.) While you're on the road, you can retrieve new e-mail onto your laptop when you go online, then sync up with the Mirra (and thus your deskop) when you get back to the office.
