Backup and Proxy Solutions to Replace Windows NT Server

Hello All,
 I am getting quite exited by all the talk of linux being a viable alternative to Windows NT. I have one group of people running Windows NT, and I am getting a bit fed up with  it, A few months ago I set up a Linux server to handle Internet mail for another research group and it works fine. So now I am looking hard a replacing a Windows NT server with linux. I have (part of) red hat linux which I mounted at home, and seems to be pretty good. So, thats the one I probably want to go with. What I am looking for is - what software should I use to do good backups. We run Cheyenne Arcserver for Windows NT servers on the windows NT server, and there is really anything it cannot do - whats the clostest thing for linux and whats the closest thing for linux thats free!!

Also - for the proxy - we are running Microsoft Proxy which has active caching amoungst other things. Whats the closest thing for linux, and whats the closest thing for linux thats free!!

Thanks in advance for your time,
Nicholas Waltham

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

There's a well-respected commerical backup program called BRU (see http://www.estinc.com) which ships with a few Linux distributions, although since I've never seen Arcserver I can't really compare them.

For proxying/caching, there's Squid (see http://squid.nlanr.net/), which is free. Actually, you can hook a Squid cache into a hierarchical network of caches, which is pretty cool and usually gets you much better connectivity to faraway places (see http://ircache.nlanr.net).

Good luck replacing NT.
