[Ftplicity-general] .cache folder

[Jeremy M. <jm...@si...>]

Can someone explain to me what the files in .cache are for exactly (other
than cache)?   I think it's all the cached PGP stuff for each individual
incremental backup?  I'm just wondering exactly what it does and what would
happen if it were deleted or something similar.  The files are of these
types for each backup:

duplicity-inc.20100624T084107Z.to.20100625T084107Z.manifest
duplicity-inc.20100625T084107Z.to.20100626T084107Z.manifest
duplicity-inc.20100626T084107Z.to.20100627T084107Z.manifest
duplicity-inc.20100627T084107Z.to.20100628T084107Z.manifest
duplicity-new-signatures.20100605T084105Z.to.20100606T084105Z.sigtar.gz
duplicity-new-signatures.20100606T084105Z.to.20100607T084106Z.sigtar.gz
duplicity-new-signatures.20100607T084106Z.to.20100608T084105Z.sigtar.gz
duplicity-new-signatures.20100608T084105Z.to.20100609T084105Z.sigtar.gz

Why are they so big?  I have one server, granted with lots of backups, but
the .cache folder is ~10GB.

Thanks,

Jeremy
