I set up tarsnap to backup one of my small small cloud servers. Some notes on the hick-ups:
- Tarsnap’s install involves compiling it – that tells you about the overall tone :). The compile requires this include file: “ext2fs/ext2_fs.h”. My little server lacked that. It took a while to find how to get it. In this case the answer was: yum install e2fsprogs-devel
- There are two keys. One is used to access your account on his server. The second is used to encrypt etc. your backups. I was puzzled about this file since I’d assumed it would encrypt the backups with one key (which would be installed on the machine(s) you backing up), and then a second key (the private key) would be used to decrypt them later. Turns out the behavior is – sort of – optional. The 2nd key you get fills both roles, and you need to use the key management tool if you want to make this distinction.
