Via the revisions you can restore a previous version of a file. We make smart revisions on every file change and those copies are kept for 30 days (since the 10.8.12 release, before that it was 14)
Go to files.billtobox.be
Select revisions in the correct Vault
Navigate to the file that want to restore
Click on the green triangular icon next to the file, this will show all the revisions of that file
Right click the version that you want to restore and select save as, download, or restore
