Question Is it safe to mount encfs via nfs on serveral machines simultaniously?


I have a question regarding my home server (running mint): There are some encfs folders with private data on the server and all data is exported via nfs to all other omputers in the house.

I can mount the encfs folders on another computer (using encfs command) to work with the data, but I never dared to mount it on more than one computer simultaniously, because I fear the encrypted data might get corrupted if more than one computer mount and access it at the same time.

So I want to ask about your experience: Is it safe to mount an encfs folder on several computers at the same time? All computers use "hard" and "sync" as nfs mount options to minimize risks of data loss. But can I access the folders simultaniously, or do I risk corrupting the encfs encryption and lose everything?

The decryption happens on the local side, encfs/nfs only exports the encrypted data. Thus, you can use it with the same caveats an any multi-user nfs mount.

Naturally, you should always back up critical data.
