What are the disadvantages of data encryption standard algorithm?

Encryption takes computer processor time. The more complex the encryption the more processing it will take.
Encryption keys can become lost rendering the associated data unrcoverable.
Encryption that is managed by the user can cause problems in a managed network by rendering necessary files unaccessable to the network managers.

As the technology is improving lot more day by day so there is a possibility to break the encrypted code.so triple des is preferred than des.though is slower compared to des it lot more secure than des

The disavandage of data encryption is when the file or your hard drive crash, it's hard to recover

The only disadvantage is that encryption is based on a key ,so if we lost that key to decrypt the data then we cannot get the readable data at the receiving end.
