The file size method is used as a preliminary method, if it fails there’s no need to do any of the more intensive checks, instead it will immediately give out an error and stop restoring. Stronger checks are used only if it passes.

The simplest and strongest check is to calculate the checksum for the entire file but this would be very intensive for large files and therefore not always feasible. A reasonable compromise would be to calculate the checksum only for certain parts of the file. This is the checksum method and it is one of the two methods that have been implemented in CRIU.
