It sounds like a bad April fool´s joke at first, but American filmmaker Dave Cooper recently filed a lawsuit against Adobe -- according to him, video files worth 250,000 dollars were irretrievably deleted from his system due to a serious bug in Premiere Pro CC 2017.1. The step has even been conceived as class action, i.e. as a class action suit in the name of all Premiere users in the US who may have been damaged by the bug at the time.
According to the lawsuit, the data was deleted in May 2017, when Cooper installed and used the then latest version Adobe Premiere Pro CC 2017.1. A bug in the software caused him to delete the media cache (clean cache) not only the (proxy) files located in this special folder, but also a large number of other footage and program files that were stored in other file folders on the same hard disk and were not used for over 90 days (for more details, see the statement of claim).
The recovery of these files is said not to have been possible -- particularly explosive for Cooper, because obviously they were not backed up elsewhere. The files are supposed to be video recordings he made from all over the world (up to 100,000 clips), which he used for commercial projects and regularly re-licensed. He puts the value of the lost data at 250,000 dollars.
The mentioned media cache bug also caused problems with other users -- it was 
officially confirmed by Adobe and fixed with version 2017.1.1. Whether the manufacturer can be made liable for any consequential damages, as Cooper tries, remains to be seen (it would surprise us).
For us, this news shows once again how incredibly important reliable and regular backup strategies are. Because no matter how, data losses unfortunately occur again and again in practice.
