While you cannot change the weather, prevent natural disasters, or stop cybercriminals targeting your business, what you can and must do is take measures to protect your business from the fallout of any disaster that may strike. This is the ultimate purpose of your data backup and recovery strategy — to provide your business with a robust set of tools and procedures to ensure your data and your business is quickly recoverable in the event of a disaster and always in full compliance with HIPAA.
As the name implies, a full backup is the backup process of making a copy of all your data to a storage device. There are several types of backup storage devices, including on-premises disks, tapes, as well as remote backup such as cloud-based backup storage.
Of all the types of backup operations, full backups provide the best data protection, as all your data is backed up and available for restoration. The drawback, however — at least when performing full local backups — is that full backups are time-consuming and require more storage space than other types of backup.
Incremental backups were designed to be a practical and time-effective solution for creating frequent backups of your data. With incremental backups, you use backup software to backup only the data that has changed since the last backup performed. The backup application tracks and records the date and time of all backup operations that occur in order to identify any files that have been modified since the last backup.
For example, on Day 1 you run a full backup. Then on Day 2 you run an incremental backup which contains all the data that has changed since Day 1. On Day 3, you run another incremental backup which contains all changes since Day 2 and so on and so on.
Since incremental backups copy smaller amounts of data than full backups, backup speeds are faster and require less media for storage. Differential backups are similar to incremental backups — the difference being that differential backups back up all changes that have been made since the last full backup as opposed to just the changes since the last incremental backup.
On Day 2, you run a differential backup, which contains all data that has changed since Day 1 so far, this is identical to an incremental backup. A full backup takes longer and requires more space than other types of backups but the process of restoring lost data from backup is much faster.
With incremental backup, only the initial backup is a full one. Subsequent backups only stores changes that were made since the previous backup. The process of restoring lost data from backup is longer but the backup process is much quicker. Differential backup is similar to incremental backup.
With both, the initial backup is full and subsequent backups only store changes made to files since the last backup. This type of backup requires more storage space than incremental backup does, however, but it also allows for a faster restore time. A mirror backup, as the name implies, is when an exact copy is made of the source data.
When obsolete files are deleted, they disappear from the mirror backup as well when the system backs up. Also, full backups take up a lot more storage space when compared to incremental or differential backups. Read more…. Incremental backup is a backup of all changes made since the last backup. With incremental backups, one full backup is done first and subsequent backup runs are just the changes made since the last backup.
The result is a much faster backup then a full backup for each backup run. Storage space used is much less than a full backup and less then with differential backups.
Restores are slower than with a full backup and a differential backup. Differential backup is a backup of all changes made since the last full backup. With differential backups, one full backup is done first and subsequent backup runs are the changes made since the last full backup. Storage space used is much less than a full backup but more then with Incremental backups.
Restores are slower than with a full backup but usually faster then with Incremental backups. Read more.. Mirror backups are as the name suggests a mirror of the source being backed up. With mirror backups, when a file in the source is deleted, that file is eventually also deleted in the mirror backup. Because of this, mirror backups should be used with caution as a file that is deleted by accident or through a virus may also cause the mirror backups to be deleted as well.
In this backup, it is not the individual files that are backed up but entire images of the hard drives of the computer that is backed up. With the full PC backup, you can restore the computer hard drives to its exact state when the backup was done. With the Full PC backup, not only can the work documents, picture, videos and audio files be restored but the operating system, hard ware drivers, system files, registry, programs, emails etc can also be restored.
Local backups are any kind of backup where the storage medium is kept close at hand or in the same building as the source.
