# Nextcloud: Document Recovery

This source provides instructions on how to recover data within the university's Nextcloud instance, distinguishing between the recovery of deleted objects and the restoration of older file versions.

## Key Recovery Methods

### Deleted Files Recovery
Deleted documents and objects can be restored via the **"Deleted Files"** section. 
- **Identification**: Users can determine the original folder of a file by hovering over the filename with the mouse.
- **Action**: Clicking "Restore" returns the file to its original location in the file system.

### Version Recovery
Users can access previous versions of a file through two different interfaces:
- **Nextcloud Interface**: Access the 3-dot menu next to the file $\rightarrow$ select "Details" $\rightarrow$ navigate to the "Versions" tab.
- **OnlyOffice Interface**: Navigate to "File" $\rightarrow$ "Version History" (Note: this is restricted to a limited number of file types).

## Trash Bin Policy and Technical Constraints
The Nextcloud trash bin operates under the following constraints:
- **Retention Period**: Deleted objects are kept for a maximum of **7 days**.
- **Capacity**: The trash bin can hold up to **50% of the user's total quota**.
- **Quota Impact**: Files stored in the trash bin do **not** count against the user's storage quota.
- **Automatic Cleanup**: When the 50% capacity limit is reached, the oldest files are automatically deleted (purged) to make room for new ones.

## Support
Technical issues are handled by the [[universitatsrechenzentrum-urz]] via the [[groupware]] ticket system or the URZ hotline (ext. 1420).
