Log shipping is the process of automating the backup of transaction log files on a primary (production) database server, and then restoring them onto a standby server. This technique is supported by Microsoft SQL Server, [1] 4D Server, [2] MySQL, [3] and PostgreSQL.
Database dumps are often published by free content projects, to facilitate reuse, forking, offline use, and long-term digital preservation. Dumps can be transported into environments with Internet blackouts or otherwise restricted Internet access, as well as facilitate local searching of the database using sophisticated tools such as grep.
RPO measures the maximum time in which recent data might have been permanently lost and not a direct measure of loss quantity. For instance, if the BC plan is to restore up to the last available backup, then the RPO is the interval between such backups. RPO is not determined by the existing backup regime. Instead BIA determines RPO for each ...

[1] [2] [3] Note for example Windows's capability to restore operating-system settings from a past date (for instance, before data corruption ...
The number of standby servers is a tradeoff between cost and reliability requirements. N-to-1 — Allows the failover standby node to become the active one temporarily, until the original node can be restored or brought back online, at which point the services or instances must be failed-back to it in order to restore high availability.
