Figure this might be a tad bit off-topic, but sent to the general questions list hoping to find anyone out there doing something similar. I was hoping to do something along the lines of cvsup or rsync, so-as to only have to sync changes daily. Here's a better picture of the scenario: ~~~~~~~~~~~~~~~~~~~~~~~~~~ File Server 1 has (roughly) 750GB Storage on RAID 5 Array, runs as a PDC using combination of Samba, OpenLDAP and some in-house utilities. This machine is very fast by comparasin to all of our other machines (dual AMD Opteron 244, 2GB RAM, running 5.3-RELEASE/amd64), and runs under minimal load/stress. Server two runs as an incoming filter for email (spamassassin/mimedefang/custom stuff using milter interface), and as a proxy server for network users during the day (running squid). This machine is considerably slower (AMD 350Mhz K62, 768Mb RAM, ATA133 disks running 4.9-RELEASE/i386), but should be adequate for the job. This machine has two 80GB disks which we'd like to use to sync data to. Ideally, we would like to backup certain directories nightly, so as to have a mirror of the important files (100-200GB or so) on the second server in the event that the first ever goes down, (essentially avoiding a tape-backup solution we cannot afford). The two machines will be connected with a dedicated ethernet link (cross cable) driectly from to each other at 100Mbps. How do I reliably synchronize the data in selected directories from one machine to the other on a nightly basis? Any ideas/suggestions/comments/questions will be greatly appreciated. -- Thank-you Nathan Vidican itstaff@wmptl.com
