As a result of system failure at me files of the virtual machine *.vbox, *.vbox-prev were gone
There were files of the virtual disks.
I added the files *.vbox, *.vbox-prev from the similar virtual machine and she earned but unfortunately all data were lost.
How to recover system to the last status? Files of pictures remained

If your VM did not use snapshots then it should be relatively easy: just create a new VM and when it gets to the disk creation step, select "use existing" and point at your existing VDI file.

If your VM did use snapshots then you'll need to use CloneVDI to recover a single VDI: put the entire chain of snapshot files (including the base VDI) into one folder and clone the oldest snapshot file. That gives you a merged VDI to which you can apply the first paragraph.

Thanks for council.
Вut unfortunately at me snapshots don't stick together with the main image. Look I can something made not so in settings?

The picture you posted shows you attemping to clone the wrong file. You need to clone the most recent snapshot file (in the "Snapshots" subfolder), NOT the base vdi file. That way you get a merged clone containing all the data up to the selected snapshot. If you clone the base you only get data from before the first snapshot.

It turned out Thanks for the help
