 This chart will deploy:
 
+- 1 NEXUS-nfs initialization container
+
+  We need this container to avoid permission issues on the NEXUS docker
 - 1 NEXUS container
-- 1 MOLGENIS-httpd container ()to proxy the registry and docker to one domain)
+- 1 MOLGENIS-httpd container (to proxy the registry and docker to one domain)
+
+## Backup restore
+There are two steps in restoring the NEXUS.
+
+- Database
+- Blobstore
+
+### Restore the database
+Go to the commandline:
+
+```bash
+kubectl get pv
+```
+
+```bash
+| NAME | CAPACITY | ACCESS | MODES | RECLAIM | POLICY | STATUS | CLAIM | STORAGECLASS | REASON | AGE |
+| ---- | -------- | ------ | ----- | ------- | ------ | ------ | ----- | ------------ | ------ | --- |
+| pvc-45988f55-900f-11e8-a0b4-005056a51744 | 30G | RWX | | Retain | Bound | molgenis-nexus/molgenis-nfs-claim | nfs-provisioner-retain | | | 33d |
+| pvc-3984723d-220f-14e8-a98a-skjhf88823kk | 30G | RWO | | Delete | Bound | molgenis-test/molgenis-nfs-claim | nfs-provisioner | | | 33d |
+```
+
+The persistent volume is the one in the molgenis-nexus namespace. 
+
+Go to the NFS-provisioner to the path of the persistent volume:
+
+```bash
+ls -t --full-time | head -7 | xargs cp ../restore-from-backup/
+```
+
+### Restore the blobstore
+You can copy the directory ```blobs``` to the target persistent volume ```/ blobs```.
+
+You can now bring the NEXUS back up.
