sync two huge filesystems
- by guettli
I need to sync two huge file systems. Both sides run linux with full root access.
My preferred solution: I can read the list of changed files and directories and sync only the changed files.
Here are some solutions and why they don't fit:
rsync: Needs to check recursively all files. There are some million files and only little changes. The check takes too long.
unison: the same: needs to check all files.
inotify: I need a handler for every directory and there too many. Inotify was not build for "watch all files" scenarios.
DRDB: Both sides should run independent.
