[ceph-users] Re: CEPH Cluster Backup - Options on my solution

Hi All I've been worried that I did not have a good backup of my cluster and having looked around I could not find anything which did not require local storage. I found Rhian script while looking for a backup solution before a major version upgrade and found that it worked very well. I'm looking for opinions on this method below. This uses stdio to pipe the data directly from rbd to a s3 host, while encrypting the data. I have a few worries. 1. The snap shots, I think I should be deleting the older one and only keeping the the last one or two. 2. Having only one full backup and diff from there seems wrong to me but the amount of data would seem to preclude creating a new full back up on a regular biases. I'm sure that others will pipe up with more issues. Note. The sum.c program is needed because s3 needs to be told about files which are larger than 5Gig and the standard tools I tested all had a limit of 32bits when printing out the size in bytes Cheers Mike
