Hi, I´m just starting to look at CEPH and some questions crossed my mind. I wonder if someone can help me with them:
1- Does Ceph use any kind of cache to improve speed access to data in OSD´s ? 2- Because Ceph is usually used for big amounts of data, how can we backup / snapshot this data ? How fast can we recover this big backup ? Or we wouldn´t need a backup at all, due to the redundance features ? Here I mean only disaster recover backup. 3- I see Ceph has an S3 API. Also, we are studying some S3 filesystems and S3backer seems to be a very nice one. What would be the differences in using one or the other ?
