Examples of backup sequences

Following are a few examples of backup sequences that support multiple restore scenarios and that you can implement to meet your SharePoint data protection requirements.

•
Full Backups only: When requirements guarantee data protection up to the previous day, performing Full Backups nightly should suffice when one or more of the following conditions exist:
•
Backup windows are large.
•
Databases are small.
•
Updates are infrequent across the entire SharePoint Farm.
•
Databases are only for testing or development purposes.
•
Full + Differential Backups: When requirements guarantee data protection up to the previous day and backups have to be as fast as possible, Full Backups coupled with Differential Backups is a valid strategy. For example, Full Backups are performed every Sunday at 11:00 P.M., while Differential Backups are performed Monday through Saturday at 11:00 P.M. Each Differential Backup includes all the changes since the last Full Backup, which is known as the differential base.
No matter when recovery is performed, the same number of restore jobs is required. For example, if recovery is performed on Tuesday, Sunday’s Full Backup and Monday’s Differential Backup must be restored. Whereas, if recovery is performed on Thursday, Sunday’s Full Backup followed by Wednesday’s Differential Backup must be restored.
Even though Differential Backups increase not only in size but in duration, restores are quicker due to the fewer restore jobs that must be run.

Performing backups

A backup using the plug-in includes the steps outlined in the following topics:

•
Selecting data for a backup
•
Setting backup options
•
Finalizing and submitting the job

Selecting data for a backup

You must use sets — Backup Selection Set, Backup Options Set, Schedule Set, Target Set, and Advanced Options Set — to create a backup job.

Backup Selection Sets are essential for Incremental Backups. Create the Backup Selection Set during a Full Backup, and use it for Incremental Backups. The backup job reports an error if you do not use a Selection Set for the Incremental Backup. For more information, see the Quest NetVault Backup Administrator’s Guide.

 
* 
TIP: To use an existing set, click Create Backup Job, and select the set from the Selections list.
1
In the Navigation pane, click Create Backup Job.
You can also start the wizard from the Guided Configuration link. In the Navigation pane, click Guided Configuration. On the NetVault Configuration Wizard page, click Create backup jobs.
2
In Job Name, specify a name for the job.
Assign a descriptive name that lets you easily identify the job when monitoring its progress or restoring data. The job name can contain alphanumeric and nonalphanumeric characters, but it cannot contain non-Latin characters. On Windows, there is no length restriction. However, a maximum of 40 characters is recommended on all platforms.
3
Next to the Selections list, click Create New.
4
In the list of plug-ins, open Plug‑in for SharePoint to view the Farm node.
5
If you are performing a Full or Differential Backup, select the Farm node.
When you select the Farm or root node, all items are automatically selected.
 
* 
IMPORTANT: When the Farm node has been selected in the selection tree, that is, all items have a green check mark with white background, select Full or Differential as the backup type on the Backup Options tab.
6
If you are performing an Individual Site Collection backup, expand the Farm node to display the Web Applications icon, navigate the selection tree to the applicable Site Collections node, and select the site collections to include in the backup.
You can select the following groups of objects:
•
All Site Collections for a Web Application
•
Individual Site Collections
 
* 
IMPORTANT: Be aware of the following:
•
If a web application does not contain any site collections, the Site Collections node does not expand.
•
When a granular set of site collections has been selected on the Selections page, that is, an individual site collection has a green check mark on a white background while the Farm node has a green check mark on a gray background, select Individual Site Collections as the backup type.
•
If there are thousands of individual site collections in the SharePoint environment, it can take several minutes to expand the Site Collection node. Quest recommends that you only use the Individual Site Collections backup type to protect the most critical site collections. If there are thousands of individual site collections, do not attempt to include them all in a single backup as including them all causes the backup job to fail.
7
Click Save, enter a name in the Create New Set dialog box, and click Save.
The name can contain alphanumeric and nonalphanumeric characters, but it cannot contain non-Latin characters. On Linux, the name can have a maximum of 200 characters. On Windows, there is no length restriction. However, a maximum of 40 characters is recommended on all platforms.

Setting backup options

The next step involves creating the Backup Options Set or selecting an existing one.

 
* 
TIP: To use an existing set, in the Plugin Options list, select the set that you want to use.
1
Next to the Plugin Options list, click Create New.
2
In the Backup Type section, select the applicable option:
•
Full: To back up the entire SharePoint Farm, select this option.
 
* 
IMPORTANT: If you selected a Farm node on the NetVault Backup Selections page, select Full or Differential.
•
Differential: To back up the data that has changed since the last Full Backup, select this option.
 
* 
IMPORTANT: When a content database is added to SharePoint SQL Server Instance following the completion of a Full Backup, Differential Backups fail and the STSADM error: “Cannot perform a differential backup for database, because a current database backup does not exist” is displayed. To avoid this error, complete a Full Backup before performing additional Differential Backups. For example, if Full Backups are performed every Sunday, Differential Backups are performed nightly Monday through Saturday, and a new web application stored in a new content database is created on Wednesday afternoon, Wednesday night’s Differential Backup fails. A Full Backup must be performed for any Differential Backup to complete successfully.
•
Individual Site Collection: To back up a subset of individual site collections or duplicate one or multiple site collections to a test environment, select this option.
 
* 
IMPORTANT: If you selected a granular set of site collections on the NetVault Backup Selections page, select Individual Site Collection.
3
In the Additional Options section, select the applicable options:
•
Number of Backup Threads: For a Full or Differential Backup, specify the number of threads that should be used during the backup; the default is 1. Microsoft’s recommended value is 3. The fewer the threads, the easier it is to read the backup log file.
•
Incomplete Backup of ALL Items Selected (only available for Individual Site Collection backups): When multiple items are included in an Individual Site Collections backup, and the plug-in is unable to back up all the selected items, the plug-in lets you specify what action the backup should take. For example, if a job includes five Site Collections and the backup of the fifth Site Collection is unsuccessful while the first four are backed up successfully, you can specify what action the backup job should take. The plug-in can do one of the following:
•
Complete with Warnings — Saveset Retained: The job returns a status of “Backup Completed with warnings” and a backup saveset is created that includes the items that were successfully backed up.
•
Complete without Warnings — Saveset Retained: The job completes and returns a status of “Backup Completed.” The errors are logged in the NetVault Backup binary logs and ignored on the Job Status page. A backup saveset is created that includes the items that were backed up.
•
Fail — Saveset Retained: The job returns a status of “Backup Failed.” However, a backup saveset is generated that includes the items that were successfully backed up.
•
Fail — No Saveset Retained: The job returns a status of “Backup Failed” and no saveset of backed-up objects is kept. That is, even if some of the objects were successfully backed up, the saveset is discarded.
•
Directory for Temporary Files: Specify the directory where temporary backup packages should be stored for SharePoint in this field. By default, this field displays the directory that you specified in the Configure dialog box. However, you can override on a per-job basis.
For Small and Scaled-Out Farms, use UNC share paths so that the SQL Server Database and search components are written to the same location. For more information, see Deploying the plug-in.
 
* 
IMPORTANT: If the backup package for the latest Full Backup has been deleted or relocated and is no longer available in the specified directory, all Differential Backups fail. Run a new Full Backup job before any Differential Backup jobs complete successfully.

Click Save to save the set, enter a name in the Create New Set dialog box, and click Save.
The name can contain alphanumeric and nonalphanumeric characters, but it cannot contain non-Latin characters. On Windows, there is no length restriction. However, a maximum of 40 characters is recommended on all platforms.
