Please document what do do if .state.gmailieer.json gets zeroed or corrupted

[sten0]

Hi @gauteh !

I recently had a moment of bad luck recently, and my .state.gmailieer.json ended up as an empty file. Presumably the thing to do in this case is to make an additional copy of .state.gmailieer.json.bak (ie: .state.gmailieer.json.bak.known_good), then cp .state.gmailieer.json.bak to .state.gmailieer.json, then gmi pull, and then let mi sync take place as scheduled.

If there aren't any pitfalls or caveats with this approach, then I'd be happy to file a PR. Otherwise I think that it would be nice if you could write something on this topic in the documentation.

Kind regards, Nicholas

P.S. "moment of bad luck" = unscheduled hard power-off when UPS failed

Alternatively, maybe lieer could handle this case gracefully and automatically instead of doing this:

gmi pull

Hi,

Yes that sounds great (a pr documenting it)! Lieer maybe printing a hint about this, but not doing it itself is maybe also good.
