| There are several data directory locations that are potentially unsafe and **likely to lead to database corruption or even data loss**. If you use any of these setups, be sure to [[:zotero_data|back up]] your Zotero data frequently. | There are several data directory locations that are potentially unsafe and **likely to lead to database corruption or even data loss**.

| * **Cloud-syncing folders**: Storing your Zotero data directory in a cloud-syncing folder (e.g., Dropbox, Google Drive, or other similar folder synchronization services) is extremely unsafe and will almost certainly lead to database corruption and potentially data loss.

| * **Network drives**: If you store your Zotero data directory on a network drive and then access it from multiple computers at the same time, you are very likely to encounter database corruption. For example, if you leave Zotero open on your laptop, then open the same Zotero database on the network drive from your work computer, you will likely experience corruption. You should never use a network drive to permit multiple users to access the same Zotero database on different machines (use [[Groups]] or [[sync|Zotero syncing]] for that). | * **Network drives**: If you store your Zotero data directory on a network drive and then access it from multiple computers at the same time, you are very likely to encounter database corruption.

| * **Virtual machines**: Similar to issues with network drives, it can be unsafe to use the same Zotero database file from both a virtual machine and the computer's host operating system (or another virtual machine). If the same Zotero database is accessed from two locations at the same time (e.g., if Zotero is open on both the virtual machine and the host operating system), corruption is likely. If you want to use Zotero in a virtual machine, it is better to set up a separate Zotero data directory in the virtual machine and to keep it up to date using [[sync|Zotero syncing]]. | * **Virtual machines**: Similar to issues with network drives, it can be unsafe to use the same Zotero database file from both a virtual machine and the computer's host operating system (or another virtual machine).

| * **Check Database Integrity:** This function checks your Zotero database for any data corruption. Database corruption is rare. In most cases, it is caused by storing your data directory in an [[#usafe_data_directory_locations|unsafe location]]. Checking database integrity can take a long time if your database is very large. If your database is corrupted, you can use the [[/utils/dbfix/|Database Repair Tools]] to repair the corruption. | * **Check Database Integrity:** This function checks your Zotero database for any data corruption.
