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.
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.
For example, backing up a single database to 4 tape drives at once. Normal backup. full backup used by Windows Server 2003. Near store. provisionally backing up data to a local staging backup device, possibly for later archival backup to a remote store device. Open file backup. the ability to back up a file while it is in use by another ...
A backup strategy requires an information repository, "a secondary storage space for data" [7] that aggregates backups of data "sources". The repository could be as simple as a list of all backup media (DVDs, etc.) and the dates produced, or could include a computerized index, catalog, or relational database.
The TSM database (through release 5.5) was a bespoke B+ tree database; although the TSM database used many of the same underlying technologies as IBM's Db2, has a SQL engine (for read-only use), and supports access through ODBC, the database had an architectural limit of approximately 530 GB, and 13 GB of log space. Starting with TSM 6.1 ...
For example, the primary might perform some computation, streaming a log of updates to a backup (standby) process, which can then take over if the primary fails. This approach is common for replicating databases, despite the risk that if a portion of the log is lost during a failure, the backup might not be in a state identical to the primary ...
Backup software are computer programs used to perform a backup; they create supplementary exact copies of files, databases or entire computers. These programs may later use the supplementary copies to restore the original contents in the event of data loss ; [ 1 ] hence, they are very useful to users.
One key skill required and often overlooked when selecting a DBA is database recovery (a part of disaster recovery). It is not a case of “if” but a case of “when” a database suffers a failure, ranging from a simple failure to a full catastrophic failure. The failure may be data corruption, media failure, or user induced errors.
