Vault Backup with empty "m" folder

Hello,
I have a backup software which backs up my vaults locally. I have now seen that the backup software does not backup the “m” folder if the “m” folder is empty. If I restore the vault without the empty “m” folder will I have any problems with the vault. I assume there will not be any problems with the vault because the “m” folder is empty but would just like a confirmation.
Thanks

Just recreate the empty “m” folder manually.
