Re: Compression and encryption

I will be using a system that's running Windows XP Pro (SP3) as a backup
target, probably using an FTP server, to back up some home and work files
-- the computer will be in a remote location (across town).

I would like to have both encryption (in case the computer gets stolen) and
compression active on the folders that the data gets backed up to. I would
prefer not to Zip the files for various reasons (such as, I don't want to
have to mass-unzip them in case the source computer loses a hard drive).

I could tell Windows to compress the files that get written to the folder,
and use a third-party folder encryption program, OR I could tell Windows to
encrypt the files, but then I would have to use something else to compress
them.

(Mode-Z for FTP only compresses the data during transfer, right? Once it's
written to the target disk, it will be stored "normally" I think.)

I would appreciate any suggestions anyone has. Thanks.

As noted, you must understand EFS if you want to successfully or safely use it. But it does rely on being able to log into the account, so if you set your PC to log in automatically, you've bypassed all the protection that encryption might offer in case of theft.

You must have strong passwords on the encrypted account, and you cannot have them set to be remembered.

And yes, you absolutely must export the certificates and understand how to re-import them. If you change the account, you must repeat this.
