Some Common Reasons Behind Corrupt Backup File

  1. Virus infection: Virus infection is one of the most common reasons for file corruption. A virus is a computer program reproduced itself and harms our computer files. Suppose we have saved our backup file inside any particular drive and a virus is present there then it may affect all the files including BKF.     
  2. Hard disk crash: Whenever a hard disk crash or damaged the data saved inside it becomes inaccessible or corrupted. And if our backup file is saved inside the system hard disk it can be corrupted. 
  3. Improper system shutdown: While working on the computer if due to power failure system turns off the computer data can be damaged. This can affect our hard disk, the applications, and files which were opened before system shutdown. 
  4. Interrupted backup process: While backing up the data if any type of interference or interruption takes place the backup file can be damaged. The interference could be anything like a sudden power failure, software collision, human errors, etc.
  5. Missing of catalog files: All the details (file size and location) of a backup file are stored in catalog files. If any catalog file is missing from backup then we can’t open it or it could be corrupted.    
  6. CRC failed: While opening or restoring data from a backup file if we receive Cyclic Redundancy Check error it means the file is corrupt and can’t be used for restoration.
  7. Error in a backup application: Sometimes the programs which are used to create backup files such as NT-Backup or any other tool can be damaged or infected by a virus. This can cause corruption in backup file.
  8. Software or hardware malfunction: Software or hardware malfunction can corrupt a backup file. Software malfunction refers to any problem such as a collision of software, virus infection, outdated software, etc. and hardware malfunction refers to a driver problem, bad sectors in a hard drive, faulty or damaged hardware devices, etc.

Avoiding Backup File Corruption- Tips and Tricks

Install an Antivirus Program– First of all, you must have a good and effective antivirus program installed into your PC that would defend the backup files from virus attacks. The antivirus software creates a wall which restricts viruses and malware from entering in the system and affecting the files.

Maintain Space in Hard Drive– Never fill your hard drive with its full capacity because the chances of hard drive crash are high. You should always delete unnecessary files from time to time from the hard drive and prevent hard drive crash. This technique will avoid backup file corruption issues as well.

Avoid Abrupt System Shutdown– It takes some time when a system is shut down as it closes all the related application first and then closes the whole system. Therefore, you must close all the application first and then shut down the whole system. Forced shutdown is not good for any computer files.

Have a Power Backup– Another reason for abrupt system shutdown is unavailability of power backup. So I would recommend that you should always UPS for a regular power supply. If in case there is a power failure, the UPS gives the backup to the computer system.

Complete the Backup Process– If a user takes the backup of data, it requires a lot of time. But some impatient user interrupts the backing process. This results in backup file corruption. Therefore, it is my personal advice that please don’t be impatient and wait until the whole backup process completes.
