smartbotic/deploy/zeus/maintenance/set-file-ttl.cpp

// Give every stored file an expiry.
//
// A file's TTL could only be set at upload before 2.8, so everything written
// before that is immortal - and FileRecord carries no expiry field, so a file
// that already has one cannot be told from a file that does not. The only
// available move is to set one on all of them.
//
// 90 days: these are working data - source photos, generated images, downloads -
// all of it either regenerable or already published elsewhere. Long enough that
// nothing in flight is lost, short enough that the store does not grow for ever.
