In accordance with GLP compliance, eLABJournal automatically keeps versions when a section is saved. To restore a previous version of a section, open the section submenu and click on the Triple bar and click on History

In the opened window, you can find a list of all versions. For every version, you can see when it was created and by who. It is easy to recover an earlier version of your data files. 

Click Restore this version to recover the selected version.

Note that recovering a version is regarded as creating a new version and the timestamp of this version is adjusted accordingly. The version history is currently supported in the text, procedure, comment, Excel, MarvinJS and Image Sections.
