 ## Restore from backup
 
 Now supposed your primary seafile server is broken, you're switching to a new machine. Using the backup data to restore your Seafile instance:
 
-1. Copy `/backup/data/haiwen` to the new machine. Let's assume the seafile deployment location new machine is also `/data/haiwen`.
+1. Copy `/backup/data/seafile` to the new machine. Let's assume the seafile deployment location new machine is also `/opt/seafile`.
 2. Restore the database.
 3. Since database and data are backed up separately, they may become a little inconsistent with each other. To correct the potential inconsistency, run seaf-fsck tool to check data integrity on the new machine. See [seaf-fsck documentation](seafile_fsck.md).
