Automatic backups
each morning right after the game's save, when you quit or close the game, right before a rebirth, an expedition or a zombie wave, when a run reaches an ending, and on a timer if you want. Every file of the save is copied and checked.
Pictures and portraits
each backup made while you play takes a picture of the game, which you can click to see full size, and each save shows its survivor's portrait.
Pause menu
Backups of this run opens the save manager over your run, and Back up now saves and backs it up.
Timeline
a save's backups and the game's day snapshots, grouped by day. Click one to see its picture, your survivor's Life, Satiety, Morale, Stamina, Planning Points, Survival Points and items then and how they changed.
Compare with now
what changed between a backup and the save as it is now, item by item.
Restore
load a backup as a new save next to the original, or replace the save. The save as it is gets a backup of its own first.
Trash
removed backups and deleted saves wait 30 days in the trash, where you can put them back.
Saves
search, sort, filter, pin, rename, write notes, duplicate a save, and turn any of the game's day snapshots into a save of its own.
Export and import
export one backup or a whole save to a .slsave file you can keep or share. Put .slsave files or loose save files in SaveBackups\Import and press Import to see what each holds and bring it in.
Steam Cloud check
if a save is suddenly behind its own last backup, the save manager shows both days side by side so you can keep either.
Keeps what matters
every backup of the last 3 days of play, then one a day, then one per loop, under a 2 GB limit by default. Pinned backups are kept no matter what. A second folder can get a copy of everything.
Settings tab
change every setting in the save manager, and it applies at once.
