Backup/Snapshot for HCV Opensource?

Moin,

yesterday something went wrong in my test installation. (I don’t know what I did wrong) but my Root CA was destroyed. I was able to restore a backup of the data directory, but it was probably lucky that it worked because the backup was made while vault was running.
Is there, similar to the Enterprise version with the raft snapshot, something similar for the file based OpenSource version?

Thanks
