I have a Western Digital external hard disk for backup purposes. What is a good syncing software that will only copy over new files since last backup?

Thanks.

I like Argentum Backup ($25) if you have a simple USB or firewire connection, and Fastback ($90) if you are using a more complex network drive configuration.

Second Copy was included free with my Apricorn drive. Its very easy to use; I'd recommend it.

$29.95 if you want to buy it as a standalone.

Start > Programs > Accessories > System Tools > Backup. Little known but powerful backup utility for Windows.

Create a list of files to be backed-up in the LH pane, and then save those file selections under the 'Job' menu. For the initial backup, do a type = Normal. For subsequent backups, do type = Incremental, and append the incremental save set to the initial backup media. You will then have one backup file containing an initial save set, and incremental save sets for all changed files. Develop a system so that once a month you create a new Normal backup file, and append incrementals to that file. Keep 13 months worth of those files, and you'll mimic how it's done in large data centers.

Try restoring a file once or twice just to see how it works.

Nothing like that in my Windows XP Home Edition. What version of Windows are you talking about?

XP Professional has it.

It's in all XP and 2000 versions (and 95/98/ME, too). See How to Install Backup from the CD-ROM in Windows XP Home Edition at

Best ever synch and back up software is SynchbackSE from http://www.2brightsparks.com/

It's like 20 bucks and so much better than ANYTHING i have ever tried, and believe me I think I have tried most of them. Check it out.

I use PowerDesk instead of Windows Explorer, and its File Sync feature works fine for backups.
