Differential and Incremental backupsWhat to choose
Differential and Incremental backups are called “Intelligent” backups. Because only a small percentage of information on a computer changes on a daily basis, running a full-sized backup every day can result in wasted time and disk space. Differential and Incremental backups allow you to backup only these changes in different ways; saving time, space and money. Keep reading to learn more about Differential and Incremental backups and why you should care about them.
What is Recommended
Most backup companies recommend a full backup weekly as part of an overall backup/data-integrity plan. Additionally, Full backups are recommended if there are major changes to a system (e.g. a change in Operating Systems, an update in software or new software installation).
Differential backups: Differential backups are based on the last full backup performed and backup all changes since the last Full backup was performed.
Incremental backups: Incremental backups are based on the last backup performed and backup only the changes since that last backup (Full or Differential).
Incremental and Differential backups
Incremental and Differential backups were both designed to allow you to backup only files that have changed, although they differ on which files are selected. Incremental backups will back up any changes you have made since your last backup (regardless of type), whereas Differential backs up all of the changes since your last Full backup.
Overall backup strategy
As part of your overall backup strategy, the option to select an Incremental backup a or Differential backup can help manage your data storage and backup job speed. For more detailed information relating to how Differential or Incremental backups differ
Enhanced Incremental and Differential backup performance
Traditionally, Incremental and Differential backups of large files and databases don’t conform to small backup windows – it just takes too long to scan, compare, and identify what’s changed before the backup can begin. The Backup Accelerator in SecuredBackup decreases the backup time of large files by 60% to 80%, when compared to a regular file-level backup of the same data.
