Answer 2

Answer:

Explanation:

Back up:

A backup, also known as data backup, is a copy of computer data that is made and kept in a different location so that it can be used to restore the original in the event of a data loss incident. "Back up" is the verb form, which refers to the act of doing so, whereas "backup" is the noun and adjective form.  Backups can be used to restore data from an earlier time or to recover data that has been lost due to data deletion or corruption.  Backups offer a straightforward method of disaster recovery, but not all backup solutions can recreate an entire computer network or other intricate configurations like an active directory server, database server, or computer cluster.

Each piece of data deemed important to save is included in at least one copy on a backup system. The amount of data storage needed may be substantial. The structure of this storage may be provided by an information repository model. Data backups of data already in secondary storage are copied into archive files using a variety of data storage technologies. Additionally, there are several configurations for these devices that can be used to offer geographic dispersion, data protection, and portability.

Back up method:

A recent archive file "mirror" of the source data is stored using the reverse incremental backup technique, along with a number of changes between the "mirror most "'s recent state and its earlier states. A non-image full backup is the first step of a reverse incremental backup technique. The system stores the information required to reconstruct earlier versions while occasionally synchronizing the full backup with the live copy when the full backup is completed. Hard links, as used by Apple Time Machine, or binary diffs can be used for this.
