Hi there, my apologies if this might have been discussed earlier. I'd like to use aufs3 in a SSD setup with rw-storage in a RAM-disk. So far so good. I'm looking for an example how to implement regularly snapshots. Say a read-only-branch for /var/log resides in a squash-fs file-system via loop-fs. After some days I may want to generate another snapshot of /var/log, stuff the current state in another read-only branch based on a newly generated loop-backed squash-fs.
How to do that? Are there good examples? I know that I can add and delete branches at run-time. One scenario would be to a) add a new read-write branch b) mark the previous read-write branch read-only c) generate a new image from the former read-write-branch d) add the new image as read-only branch e*) remove the old read-only branch f*) remove the old read-write branch e*) and f*) will probably not work directly, as some files are still held open by syslogd etc. Of course, one could keep a history of file-sytems and periodically try to delete branches. Finally old branches could be removed. Is there a better way? Thanks.
