using dd as a server backup plan

I am working with 3 servers(exchange, DC, DNS) all of which have raid 5, and the owner wants a backup plan that is "CHEAP" and reliable. I have experience with dixml, but would like to hear your input on what I should use for a backup system. I have no experience with dd but have heard that I could use that as an option after I learn how to use it... Any input is greatly appreciated!!!

From what i understand dd is a linux only application.

You say CHEAP and reliable but i dont know if you are going to get a sufficient amount of both. You can go cheap but most of the free or inexpensive software out there is buggy. I wouldn't trust my corporate servers with something like that.

The reliable software out there (Norton Ghost and Acronis True image) are very reliable but are a little on the pricey side. But those are what i trust on my corporate network.

Either way you go make sure you fully test your backups to insure they will work in a disaster situation.

dixml is not an a corporate/enterprise level solution

Reliable solution install a DAT drive into one of the servers probably the DC then setup backup routines by sharing files and folders of the other servers. You may use microsofts NT backup util however using athird party with network plugin agents and connectors will do the job better.

Cheap solution get your self 6 USB drives they are cheap set 1 and set 2 stick in set 1 on day 1 then sticking set 2 and taking set 1 offsite.

I stand corrected. dd can be used on a bootable linux distro such a Knoppix to backup a server.

Additional suggestions:

I dont think i would use an imaging solution on an active Exchange server. Check out a post that i started several months back for reasons why.

https://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/Q_23312935.html

The issue with imaging software is you only get a "moment in time only" backup so if anything has change since your last image and has not been backed up any other way then it is lost. I have looked into Acronis's differential backup feature but have not tested it.

What i have done to speed up the recovery of my restores is create a base image of my servers with just Server2k3,  updates and needed programs. AD, DNS,DHCP ect... are all backed up by Backup Exec (could also use NTbackup). I can then take that backup and restore the needed services after reloading the base image.

guitarist5377:I appreciate your input, and believe that I will attempt to put these options into place; although I  would like to know if you would you trust Bacula or BackupPC to backup an exchange server with a raid 5 configuration?
guitarist5377

RAID 5 should not matter to either program, because a RAID array looks just like a single drive to them.

Doing a bit more research with regards to backup solutions specific to exchange, I came across this link:
http://www.msexchange.org/tutorials/Exchange-2003-Backup-Restore-NTBACKUP.html

It looks like it might be a little closer to what you want, since it is a utility already built into exchange.  I would say that this is probably more reliable of a solution for exchange than other options, simply because it is designed for this, and is not a 3rd party solution.

I still stand by my recommendations above for any other type of backups, however...
