There are several implied references here to likely problems with rsync and how they are all deal breakers. I've been trying to find a solution to this problem for weeks and have not found any direct documentation or evidence to support what is being said here. I'm not skeptical, though, I just need to understand what's going on.
Rsync is the only option for me, and I'm rather confused by the other solutions floated in this and other threads. On-site backup is precarious and viable only in a datacenter type situation imho. What about the fire scenario? Getting the data somewhere else is crucial, and in my case I am limited to rsync through rsh. I'm running rsync 3.0.6 but the server is 2.6.x. I have ~ 1.9 files found by rsync and it always fails on some level. I use -aH but it randomly exits with an unknown error during remote comparison or the initial transfers. During the transfer phase it says its sending data, but nothing shows up on the server. The server admins are not aware of any incompatibility with their filesystem and the internet does not seem to deal with this problem, which brings me back to the initial question. What does one use if not rsync? There's no way to justify or implement backing up the entire pool every time without a lot of bandwidth, which I don't have. What exactly is rsync's problem? Do I really need to shut down backuppc every time I want to attempt a sync or would syncing to a local disk and rsync'ing from that be sufficient? I'd really like to know the specifics of the hardlink and inode problem talked about in this thread like how to find out how many I have and what the threshold is for Trouble and how the rest of the community deals with getting pools of 100+GB offsite in less than a week of transfer time. Lots of info requests, I know, but I really appreciate the help. My ISP and all the experts I've tapped are completely stumped on this one.
