Help with Backups and Encryption

[huddadudda]

I have been asked to figure out how do a weekly full backup of our companies Mission Critial Sensitive Private Data (employee files and such) - then on a daily basis do incremental backups. All which need to be ftp'ed remotely to an offsite backup server housed at another location in case of emergancy or natural disaster. It is also required to have the remote ftp remove the backups after 30 days old automatically - to save space and so that you dont have to manually do it.

So I am looking for help with the following:

- Create a self extracting archive, drive image or any type of archive w/512 Bit Encryption or better, whatever is best that I can get of files, masking or encypting the filenames from being viewed or expanded, then FTP them daily to a remote site via SSL for once a week full backup of "mission critical" items.

- Then again the sames as above but on a daily basis doing incremental backups or differencial backups of files that have been changed or modified since the last backup.

- Automatically remove the backups after "X" amount of time from the ftp.

Is there any software that can do this and if so can someone point me in the direction how to set this up or give me the setup instructions how to do so? Thanks in advance!

Also on a side note - I am looking for a way to encypt that same data on our network drive so that users must be setup to access that drive and if someone was to pysically come in and steal the drive they could not install it in a computer and "see" the data. Any help for this would be appriciated too!

How big are the backups?

How much network bandwidth do you have?

Have you ever thought about replication?

Never thought about replication because I dont know much about it. I have about 40GB of bandwidth to use each month and my FULL backup is only 1GB at best right now. Incrementials would be around 10-25MB so I will be within my bandwidth limits fine. I just have sensitive data that must be ftp'ed to another location in case of emergancy. Disk images are taken of each computer monthly so no worries there. Which also brought me to the point of possibly making the drive encrypted.

Right now we are only doing full monthly backups, once a month for the day I spend making images of each machine, only 4 right now though but will grow. I am using winrar to compress the data and then it masks the filenames and uses 256Bit encryption. But I cant do incrementail backups with it. So any file changes or additions are missed. Plus I dont want to transfer 600MB each day!
