Hi, has there been any thoughts on utilizing posix_fadvise* in BackupPC?
Let's assume for a moment you have a really big pool where the speed of pool operation improves dramatically when the directory structure is cached in the linux file system cache. Now backuppc starts to backup a client and because of not using posix_fadvise each file written to disk is being cached in the file system cache, eventually pushing the cached directory structure out of the cache. In the end i'm interested in keeping my directory structure in the file system cache instead of files backupped from clients that are not touched again any time soon. Any ideas on using https://github.com/Feh/nocache with backuppc?
