backups
Files saved twice
Backups are copies of data stored separately from the original, kept as protection against loss or corruption: Make sure you have backups before updating the system.
The term extends to anything held in reserve—backup plans, backup generators, backup singers.
In traffic, a backup is congestion or blockage: There's a backup on the highway.
