Then remind your customer to tell rsync to inspect the data rather than trusting time stamps. Rsync will then run quite a bit slower but at least it will catch a corrupted file. There is still the problem that the client OS may have cached data which it thinks is correct but no longer matches what is on the server. This may result in rsync making wrong decisions. A better approach is to run rsync on the server so that there is rsync to rsync communication rather than rsync to NFS. This can result in far better performance and without the NFS sychronous write problem. For my own backups, I initiate rsync on the server side and have a special secure rsync service set up on the clients so that the server sucks files from the clients. This works very well and helps with administration because any error conditions will be noted in just one place.
