A reverse incremental backup method starts with a non-image full backup. After the full backup is performed, the system periodically synchronizes the full backup with the live copy, while storing the data necessary to reconstruct older versions. This can either be done using hard links—as Apple Time Machine does, or using binary diffs.
A database dump contains a record of the table structure and/or the data from a database and is usually in the form of a list of SQL statements ("SQL dump"). A database dump is most often used for backing up a database so that its contents can be restored in the event of data loss. Corrupted databases can often be recovered by analysis of the dump.
True continuous data protection is different from traditional backup in that it is not necessary to specify the point in time to recover from until ready to restore. [5] Traditional backups only restore data from the time the backup was made. True continuous data protection, in contrast to "snapshots", has no backup schedules. [5]
Site-to-site backup. backup, over the internet, to an offsite location under the user's control. Similar to remote backup except that the owner of the data maintains control of the storage location. Synthetic backup. a restorable backup image that is synthesized on the backup server from a previous full backup and all the incremental backups ...
A full backup of a large data set may take a long time to complete. On multi-tasking or multi-user systems, there may be writes to that data while it is being backed up.This prevents the backup from being atomic and introduces a version skew that may result in data corruption.
The vague adjectives of very and large allow for a broad and subjective interpretation, but attempts at defining a metric and threshold have been made. Early metrics were the size of the database in a canonical form via database normalization or the time for a full database operation like a backup.
Veeam Backup & Replication operates both the virtualization layer as well manages physical machine backup. It backs up VMs at the image-level using a hypervisor's snapshots to retrieve VM data. [6] Backups can be full (a full copy of VM image) or incremental (saving only the changed blocks of data since the last backup job run). [7]
This is a list of notable backup software that performs data backups. Archivers, transfer protocols, and version control systems are often used for backups but only software focused on backup is listed here. See Comparison of backup software for features.
