Eek, sorry!

Hmm, how do you do your backups? Is there a segments_N file present in the backup? It's somewhat spooky that you have a write.lock present because that means you backed up while a writer was actively writing to the index which is a bit dangerous because if the timing is unlucky (backup does an "ls" but before it can copy the segments_N file a commit has happened) you could fail to copy a segments_N file. It's best to either pause the writer for backpus to occur (simplest) or make a custom deletion policy that safely allows the backup to slowly copy even while indexing is continuing (advanced). > However, if I start up my indexer with that directory it shrinks to a > fraction of its size (500 times smaller) and (obviously) contains > virtually no documents.

Maybe try other (older) backups to see if they have the segments_N file?
