I have the hardware ready, but I need the software. I have read the other questions here on EE and I have researched through Google, but I would like to get other opinions. I think I will need two programs: for bare-metal recovery and for data-only.
I have one machine to make the Backup Server. It is older and slow but has new, big HDDs.
I have three (maybe will become four) servers to backup. The IT staff is just me, and we cannot hire contractors, so I want a dependable solution that won't demand a lot of time to restore a server.
I am using a home-made rsync solution that my predecessor put in place, but it cannot be used for bare-metal recovery, and I have to manually prune the current backup server when it becomes full.
I will be backing up the data nightly to the backup server, which will be housed in another building on campus. Also, I will be archiving database dumps to removable HDDs and storing them in the safe. The legistics of the operation are sound and in place, but I cannot decide on hardware.
I know that rsnapshot would give me a no-prune rsync solution. I know that many recommend Amanda and Bacula. I have read that Acronis does images and even DVDs to backup the server, but I don't know if Acronis works on RAID machines. I have heard of Mondo as well.
Advice and recommendations, please.
