I wrote some scripts based on this page.
https://ceph.com/dev-notes/incremental-snapshots-with-rbd/ [1] We export the whole image to an external array, then export daily diffs. The array is then rotated weekly. Even with "--rbd-concurrent-management-ops 20" it is a very slow export/import process. We are discussing changing the process after having to restore some data recently. We are going to export to a second Ceph cluster as a standby cluster. Then export to an external array for off-site storage. Hope that helps, Chris On 2015-09-22 6:38 am, J-P Methot wrote: > Hi, > > We've been considering periodically backing up rbds from ceph to a > different storage backend, just in case.
