Save time when you need it most by quickly performing point-in-time restores of your Microsoft SQL Server databases, tables and transactions. Instant visibility into your Exchange backups provides easy granular searches, fast recovery of individual objects and more without restoring the entire database. Enable fast object-level recovery for Active Directory from a single-pass backup or storage snapshot without additional tools or the need to restore an entire machine.

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.

SQL Server database migration methods. Applied per database Can be delayed. Applied to a set of user databases Can be synchronous or asynchronous Secondary database is readable SQL Server Enterprise edition only Supports both automatic and manual failover Failover can be initiated for multiple databases at a time, at the database group level. Supported in SQL Server Standard edition Applied to a single user database per availability group Can be synchronous or asynchronous Supports both automatic and manual failover Failover can be initiated at the availability group level Can be used as a hybrid environment between on premises and AWS.
Supports migration of a set of objects tables, view, stored procedures Supports asynchronous replication with near real-time data Subscriber database is readable Requires close monitoring of SQL Server replication jobs that perform the replication. Highly automated lift-and-shift solution Agent-based, block-level replication. Supports full load and CDC Supports all database sizes. Supports small databases Requires downtime Schema is pre-created at the destination Used for moving data, but not metadata.
No backup needed Requires downtime Involves stopping, detaching, copying files, and attaching to Amazon EC2. Document Conventions. Migration strategies. Did this page help you?

SQL Server database migration methods
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.
Backup and Restore Strategies in SQL Server â Part 1
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. Reducing backup time increases the available window to perform other critical SQL Server tasks.
You can change your cookie settings at any time. Vysiion's Exponential-e Cloud Backup service provides a single solution for each distinct backup and recovery requirement in your organisation. Back up your databases, files, applications, endpoints and VMs with maximum efficiency according to data type and recovery profile.

Backup and restore methods available for MS-SQL server databases
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.
Customers are responsible for arranging the backup of their data if their systems are not being hosted by FileHold Systems. This guide is intended to assist you to create a backup plan for your data that is stored in your FileHold system. We are happy to review your backup and restore strategy as part of your current FileCare agreement.
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. The full backup is triggered on February 1, , and a snapshot is created at PM when the job is successful.
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.
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. Some may even argue that having multiple working copies of the data somewhere else removes the need for having backups, but in a not-so-perfect world, backups are still required to make sure you can always recover from data mishaps.
