What is a mirror backup?
A mirror backup is a backup type similar to a full backup but one where the backup is not stored in a compressed zip file.
Mirror backups are the fastest to create because they do not get compressed.
Some advantages of mirror backups include:
- Restoring files is easy; simply browse through the mirrored folder to get the desired file.
- Backup creation is faster than that of full, drive image, differential, or incremental backups.
Some disadvantages of mirror backups include:
- Because mirror backups aren’t compressed, they take up more storage space than some of the other backup types.
- Mirror backups lack some of the added benefits of other backup types such as backup testing, encryption, and compression.
