As far as I know, Foldershare only stores during transmission. For my web stuff, I share to both my work machine and my home machine for a little redundancy.

Then, if I use a service like s3, the prices won’t be so bad.

Will, I’ve used FolderShare before to synchronize files between computers. Are you saying they can store the files on their servers now?

Pros: Fully automated backups and LAN-speed restores
Cons: No backup support for Linux PCs, cost ($400+ dollars for PC+disks+software)

The biggest issues with foldershare are 1) there’s no going back farther than the previous backup and 2) the application runs under a user account and 3) you can’t point it directly at your virtual directories.

You have to do some scheduled task magic to get this working. Here’s what I did for my webserver:

1) created an account and added both my web server and home machine to a shared private folder
2) created a scheduled task on the web server that, every evening, copies all files from my virtual directories to a backup folder. This backup folder is then shared via foldershare.
3) On my home machine I set up a scheduled task that regularly takes a snapshot of the foldershare directory, making a backup of the backup, so to speak.

So the shared folder gets a new copy every day, which is archived online, and I take a weekly snapshot of this for longer term storage. I do have to remain logged into the web server, which kinda sucks as its a low memory virtual private server.

Some possible improvements to this:
1) Write a small app to save a copy of all files you wish to backup to a dated subfolder of the foldershare folder, so you have, say 7 backups for the previous week. Share the root of this directory.
2) create a scheduled task that runs the foldershare app under your user account that waits an hour for it to complete and then kills it. The FS app is a tray app, so I’m not sure how well it would function as a scheduled task (I don’t know if scheduled task apps throw when attempting to create UI).
