Backup And Restore - Single Node

I’ve got a few questions about xcopy backup and restore of single node eventstore instance

The documentation says that for the restore you should copy chaser.chk to truncate.chk and then copy “the rest of the files”

Does “the rest of the files mean”

  • only the chunk files

  • all files excluding “truncate.chk” but including the backed up “chaser.chk”?

Also, do you have to stop the single node instance when doing

  • the backup?

  • and restore?
