However, unlike incremental and differential methods, the updated data becomes part of the full backup without needing to re-upload the entirety of the information. When it becomes time to set up another full backup, this method compares the files that have changed since the last full backup and only uploads the changes necessary. Synthetic full backups operate by completing an initial full backup, as well as additional incremental backups. This method also requires an initial full backup before starting incremental backup, and a failure on any backup level leads to incomplete recovery. You are required to locate files within multiple backup sets, and all increments are necessary for full recovery, making restoration a slow process. Incremental backups can take much longer to recover a specific file. Incremental backups allow for fast backup windows, less storage space, and retention of several versions of the same files. However, incremental backups only back up any changes that have happened since the last full or incremental backup, unlike a differential backup, which regularly backs up all changes since the last full collection of data.
Incremental BackupĪn incremental backup also operates on a much more frequent timeline than a full backup. Restoring a single file is also more difficult, because you need to locate it within the multiple backup sets.< 3. In the event of a backup failure for the initial full set of data or even one of the differential pieces, you will have an incomplete recovery. It also requires an initial full backup before the differential process can begin. Needless to say, over the time, differential backup will become bigger than the full backup and less efficient. However, this method still suffers from slowness comparing to incremental backup. When paired with a full backup, a differential backup will provide many more options, take up less storage space, allow for retention of several versions of the same file, and give you easy access to data, if a restore is necessary. Instead of backing up all data, this method instead backs up new copies of any files that have changed since the last full backup. Join Us – Webcast: Advanced Backup and Recovery with the CloudBerry & Wasabi Cloud Storage SolutionĪ differential backup is one of the solutions to the void created by spacing out full backups. However, this can leave gaps for data created or changed between recovery points. Many also choose to conduct full backups on a weekly basis. This type is best for when you’re creating your initial backup files and when major updates occur. Piece of available data every single time, a full backup takes much more storage space, bandwidth, and time to complete. On the downside, though, since you’re backing up every You can also easily have all data in one backup set, so it’s easy to setup, differentiate versions of data from each other and reliable. This means that you have everything you need ready in its entirety for access if you need it. Full BackupĪs one of the tried and true methods of backup, a full backup means that all data you want to recover becomes backed up in the storage space. To help you find the best strategy for your information, here are the four most popular types of backup. There are multiple backup methods you can use, both for your initial backup and any updates to your data.
