Before Phoenix can back up your databases, you have to configure your server for backup and restore. When a full backup is triggered based on the backup policy, Phoenix agent communicates with the SQL writer service using the VSS framework. When the backup job is successful, Phoenix creates a snapshot Restore Point in your storage. All snapshots created within the number of days specified under Retain Daily Snapshots for are retained. Suppose you have chosen to retain daily snapshots for 10 days. Between February 1, , and February 28, , Wednesday falls on 1st, 8th, 15th, and 22nd.
You can choose these methods based on your assessment and requirements. This section describes some of the most common methods, which are summarized in the following table. Failover can be initiated for multiple databases at a time, at the database group level. Always On availability groups section. Not covered in this guide see Basic Always On availability groups for a single database in the Microsoft documentation. Distributed availability groups section. Requires close monitoring of SQL Server replication jobs that perform the replication.
This is why a good, and tested, SQL Server backup and restore However, with the tools, scripts, and techniques provided in this book, and with the Chapter 8 – third-party tools such as Red Gate SQL backup aren't free, but they do.
Database administrators need a robust SQL Server backup and recovery solution that significantly reduces SQL Server backup and recovery time, minimizes storage requirements, and provides enterprise management capabilities to conduct backups across a large number of SQL Servers simultaneously. SQL Safe Backup has been specifically designed to meet these requirements, resulting in increased application and business availability for critical SQL Server infrastructures. Advanced compression, disk writing, and multi-threading technologies significantly increase the backup speed.
In a manner of speaking, planning and implementing a SQL Server backup design is an art. Backup is probably the simplest and the most familiar process in most situations. A backup copy is used to recover data needed to restart an application correctly, after certain types of failures. Using various tools and techniques, the data is replicated to different geographies and is made available all the time.
MS SQL. While these high availability solutions ensure maximum uptime for your databases, you need to setup backup and restore strategies to recover the data or minimize the risk of data loss in case a failure happens. There are a variety of failures that can occur at various stages of the life of the solution. In some of the cases, there are some third party tools to recover a transaction or a group of transactions from transaction log assuming you have non-truncated transaction log file but in some other cases where the disk itself got corrupted requires you to rely back on backup files. Based on your need, you can choose either a simple backup process if data loss is acceptable to some extent or a bit of a complex backup process if you want to have capabilities in hand to recover to the point-in-time in case of any failure. These are the different types of backup SQL Server allows:. Full database backup takes a copy of the entire database basically copies all of the pages including the part of the transaction log file so that the full database can be recovered after a full database backup is restored.
for SQL Server and security considerations for SQL Server backup and restore. systems, see Hardware and Software Requirements for Installing SQL Server. For Best Practices for Using Differential Backups with a Read-Only Database.
Database systems , like any other computer system, are subject to failures but the data stored in it must be available as and when required. When a database fails it must possess the facilities for fast recovery. It must also have atomicity i. There are both automatic and non-automatic ways for both, backing up of data and recovery from any failure situations.
Save time when you need it most by quickly performing point-in-time restores of your Microsoft SQL Server databases, tables and transactions.
