Save folder structure

Hello,

I'm restoring the map because of a problem with an plugin

In the "Save folder\Procedural_Map.." there are 6 files , Why ?
Are they 6 backup files?

I ask that , because I tried to replace 0.sav ( the most recent 05:40pm) with 1.sav (about half an hour before 05:15pm, then before the issue)
and unfortunately I lost the last building built the day before !

I'm confused , maybe you could give me a little hint ?
Thanks

 

The server saves the world on a set interval, each time this autosave occurs 6.sav will be removed, 5 will be renamed to 6, 4 to 5, and so on and then the current state will be saved to 0.sav
When loading one of the backups you should however only lose what was built between the time of the backup and the time when restoring the backup, you shouldn't actually lose buildings from before that.

 

As regards the backup I believe it was my fault . The issue is occured before the last backup Thank you for your clarification
