Microsoft sql server backup script

Click one of the following tabs for the syntax, arguments, remarks, permissions, and examples for a particular SQL version with which you are working.

SQL Managed Instance. If a list of files and filegroups is specified, only those files and filegroups are backed up. During a full or differential database backup, SQL Server backs up enough of the transaction log to produce a consistent database when the backup is restored.

Only a log backup can be restored to a specific time or transaction within the backup. LOG Specifies a backup of the transaction log only. The log is backed up from the last successfully executed log backup to the current end of the log. Before you can create the first log backup, you must create a full backup.

The log is truncated after all the records within one or more virtual log files become inactive. If the log is not being truncated after routine log backups, something might be delaying log truncation. For more information, see Factors that can delay log truncation.

Under the simple recovery model, a filegroup backup is allowed only for a read-only filegroup. Consider using file backups when the database size and performance requirements make a database backup impractical. The NUL device can be used to test the performance of backups, but should not be used in production environments. The number is unlimited.

For more information about partial backups, see Partial Backups. The logical name must follow the rules for identifiers. Specifies a disk file or tape device, or a Microsoft Azure Blob storage service. The NUL disk device will discard all information sent to it and should only be used for testing. This is not for production use. Starting with SQL Server The NUL device will discard all input sent to this file, however the backup will still mark all pages as backed up.

For more information, see Backup Devices. Avoid using this feature in new development work, and plan to modify applications that currently use this feature. In order to mirror backups to devices that have different sector sizes, the BLOCKSIZE parameter must be specified, and should be set to the highest sector size amongst all the target devices.

Used to create an Azure snapshot of the database files when all of the SQL Server database files are stored using the Azure Blob storage service. A consistent set of Azure snapshots make up a backup and are recorded in the backup file.

With SQL Server Snapshot Backup, after the initial full backup that is required by SQL Server to establish the backup chain, only a single transaction log backup is required to restore a database to the point in time of the transaction log backup. Furthermore, only two transaction log backups are required to restore a database to a point in time between the time of the two transaction log backups.

A differential backup usually takes up less space than a full backup. Use this option so that all individual log backups performed since the last full backup do not have to be applied. For more information, see Differential Backups. Encryption is recommended practice to help secure backup files. The list of algorithms you can specify are:. If you choose to encrypt, you will also have to specify the encryptor using the encryptor options:.

No additional encryption happens for the data itself. The backup fails if the database was not encrypted or if the encryption was not completed before the backup statement was issued.

A copy-only backup is created independently of your regularly scheduled, conventional backups. A copy-only backup does not affect your overall backup and restore procedures for the database. Copy-only backups should be used in situations in which a backup is taken for a special purpose, such as backing up the log before an online file restore. Typically, a copy-only log backup is used once and then deleted.

The differential bitmap is not updated, and differential backups behave as if the copy-only backup does not exist. Subsequent differential backups use the most recent conventional full backup as their base.

The copy-only log backup has no effect on the log chain, and other log backups behave as if the copy-only backup does not exist. For more information, see Copy-Only Backups. At installation, the default behavior is no backup compression. But this default can be changed by setting the backup compression default server configuration option.

For information about viewing the current value of this option, see View or Change Server Properties. The string can have a maximum of characters. Names can have a maximum of characters. If NAME is not specified, it is blank. If neither option is specified, the expiration date is determined by the mediaretention configuration setting. For more information, see Server Configuration Options. These options only prevent SQL Server from overwriting a file.

Tapes can be erased using other methods, and disk files can be deleted through the operating system. For information about how to specify datetime values, see Date and Time Types. If a media password is defined for the media set, the password must be supplied. INIT Specifies that all backup sets should be overwritten, but preserves the media header. If INIT is specified, any existing backup set on that device is overwritten, if conditions permit.

By default, BACKUP checks for the following conditions and does not overwrite the backup media if either condition exists:. This is the default behavior. FORMAT causes the backup operation to write a new media header on all media volumes used for the backup operation.

The existing contents of the volume become invalid, because any existing media header and backup sets are overwritten. Formatting any volume of a media set renders the entire media set unusable. For example, if you initialize a single tape belonging to an existing striped media set, the entire media set is rendered useless.

If it is not specified, or if the SKIP option is specified, there is no verification check of the media name. Stopping the Kiwi Syslog Daemon Service failed!!!

Second, why not use SQL server's built-in backup tools?

Why write a custom script? I agree with Bill. You should not be using a shell script. SQLExpress can be backed up live. Edited by jrv Thursday, April 17, PM. Therefore, you have to take a different approach to back up your databases when you use these editions. Currently SQL Server Express users can back up their databases by using one of the following methods:. For more information on how to use these tools to Back up a database review the following links:.

Create a Full Database Backup. Tutorial: Back up and restore databases using Azure Data Studio. In SQL Server and lower versions, the utility is shipped as part of the product. For more information, review sqlcmd Utility. In a text editor, create a batch file that is named Sqlbackup. For database recovery, you could refer to restore SQL database from bak file. Sometimes you may want to back up a database frequently and keep different versions for recovery needs, and it would be very convenient if the bak file name can be composed of database name and backup date.

Fill in your own backup path and database name, you will get a bak file with date. And the created backup files will be automatically named as database name plus date. Note: This function is only available in non-Express editions. In the General tab of New Job window, enter the name and description for the job. Click on Steps tab, hit New… and give it a Step name , then copy your backup script into Command section and click OK.
