I had no snapshot. I just wanted to try the as-of mount. I read the
manual but failed to understand it. hammer(5) says:

'Prior versions of files or directories are accessible by appending @@

I could not access them this way.

The file system by default will update historical information of a file upon every sync. You can list the prior versions of any file with 'hammer history <file>'. These are the versions that could be accessed by appending @@0x<id>. Pruning will free this space again.


But as Matt notes, snapshots are the common way of accessing historical data. I've updated hammer(5) to be a bit more clear about this. If you still feel it's unclear, please let me know.
