Restore from directory no database

I just have the storage directory left (seafile-data/storage)
it is 150gig of data. But if i copy the whole lot into a newly installed server it does not pop up.
Can i restore these files?

Without a backup from the seafile databases (see: Backup and Recovery - Seafile Admin Manual) you can not import the data to a new seafile server.

You should be able to recover all unencrypted libraries with the seaf-fsck tool, see: Recover seafile data from filesystem ยท GitHub
