Redis: Redis is a vital-price retail outlet that may be designed to cope with massive amounts of data using a superior degree of framework. It is commonly employed for true-time data processing and is also perfect for managing superior amounts of concurrency.
From this, it is actually sensible that a transaction log backup can't be completed In case the database is in Straightforward method. It only works with Total or BULK LOGGED recovery products.
Restricted querying and indexing: NoSQL databases may not assistance as effective or as versatile querying and indexing abilities as SQL databases. This could make it more difficult to accomplish specific types of queries or to find particular data.
Now that We've developed a filegroup, Enable’s check out how we may take a backup of individual data files or filegroups and also every one of the documents or filegroups in a very database. Once more we’ll have a look at executing this using the GUI or T-SQL Server specifically.
Scalability: NoSQL databases are intended to scale horizontally across several servers or nodes, generating them great for dealing with significant quantities of data and substantial amounts of concurrency.
