As a MongoDB user, it’s crucial to ensure that your data is safe and secure in the event of a disaster or system failure. Regular database backups are essential to protect against data loss caused by system failures, human errors, natural disasters, or cyber-attacks. Why are MongoDB database backups important?

SQL Server relies on Forced-Unit-Access (Fua) I/O subsystem capabilities to provide data durability, detailed in the following documents: SQL Server 2000 I/O Basic and SQL Server I/O Basics, Chapter 2. Durability: “In database systems , durability is the ACID property which guarantees transactions that have committed will survive permanently.

Note: We received feedback that there was some confusion on us calling this functionality “tail of the log caching” because our documentation and prior history has referred to the tail of the log as the portion of the hardened log that has not been backed up.

Fragmentation is a common concern in some database systems. The principle of locality While the principle of locality is usually related to processors and cache access patterns, it also applies to data access in general. The freed space will not return to the file system but will be reused by new pages. What is fragmentation?
