What is a full backup?
A full backup is a comprehensive backup method.
In a full backup, a copy of all the files you select is made. This means that each time a backup runs, an entire copy of every file is backed up regardless of whether changes to that file have occurred or not.
Some advantages of full backups include:
- Backups are easy to create and are usually faster to restore( minimal time to restore ) because all the backup files are bundled together in one set.
- Managing different versions of backed up data is straightforward.
- Backups have no dependencies on each other.
Some disadvantages of full backups include:
- Backups take relatively longer to create because each and every file is backed up regardless of whether it has changed or not in the last backup i.e. unchanged files are backed up.
- Backups require considerable storage space ( relative to the size of the source ). Because each file is backed up regardless of whether it has been modified or not. Full backups are not particularly storage space efficient.
