Can I individually restore list resource type, resource or reservations?

To restore sites created using a Room Equipment Reservations template, it is recommended to Restore a SharePoint Server Site Collection from the database backup set level. Restoring individual lists, such as Resources, Reservations, and Resource Type is not supported unless the site and lists exist and they are restored in the following order:

  • Items from List Resource Type
  • Items from List Resources
  • Items from List Reservations

Why am I unable to back up data that was created using a third-party feature?

It is recommended to verify if the particular third party feature is currently installed. If it has been uninstalled then backup is not supported for the data, which was created using the third party feature.

Why are documents in the CommCell Console a different size than the same documents in the SharePoint user interface?

While browsing documents in CommCell Console, the size of documents may not match the size that appears in the SharePoint Server User Interface. This is due to metadata being backed up with the document, which artificially could increase its size.

What do I do when I upgrade the SharePoint server to a newer version?

The system automatically detects and displays the newer version in the CommCell Console after the next backup runs.

When does a non-full backup automatically get converted to a full backup?

A non-full backup is automatically converted to a full backup in the following situations:
  • First backup of the subclient.
  • Promote a secondary storage policy copy that is not synchronized with a primary copy (for all the subclients of a storage policy).
  • CommCell Migration operation.

Why do site collection backups have low or no deduplication ratio?

For each site collection backup, the SharePoint backup API generates a file that contains data for the entire site. If data is modified in between backups, the new API generated file does not have repeated blocks of data from the previously generated file.

Are there size limits on site collection restores?

It is recommended to limit the size of site collections to 100 GB for SharePoint 2010 and 2013. For SharePoint 2007 the limit for Site Collection is 15 GB.

Are cross-application restores supported?

No. Cross-application restores of databases between different versions of SharePoint Servers are not supported. Also, restore operations across clients with different Windows SharePoint Services (WSS) Service Pack levels are not supported.

Can I restore SharePoint data to a different client?

Yes, as long as the destination client meets the following criteria:

  • Resides in the same CommCell as the client whose data was backed up.
  • Has the SharePoint Server iDataAgent installed and operational.
  • SharePoint Server version is the same as that of the source client.
  • Either in the same domain as the original server, or in a domain that has the proper trust relationship established both with the original domain, as well as all of the domains with which the original server’s domain had trust relationships.

What happens when a new subclient has the same name as a deleted subclient?

In cases where a new subclient is created with the same name as a deleted subclient, the system will append a Unix time stamp to the deleted subclient's name in data protection job history reports and views to distinguish the two subclients. For example, subclientname_1104257351.

I am using SharePoint 2007, and I am unable to see Alternate Access Mapping for the non-default zones?

Backup and restore of Web Application's Alternate Access Mapping is not supported for SP2007.

It is recommended that you document the Alternate Access Mapping (AAM) settings.

In order to do this, export your AAM settings to a text file by using the command stsadm -o enumalternatedomains.

Back up the text file by using the File System iDataAgent. For example:

Write the AAM settings for the Contoso site to a text file on drive C. stsadm -o enumalternatedomains -url http://contoso:1234 > c:\aambackup.txt

After running a restore from the CommCell Console, ensure that you recreate the AAM.

Why is the Index Cache larger in size in V10 as compared to the Index Cache that was created in the previous version?

In the previous version, meta data of each folder was stored in the Index Cache. Whereas, in V10 meta data of each file is stored in the Index Cache. Therefore, with an increase in the number of files that are being backed up the size of the index cache will increase too.

For example, Index size for a site with 5 libraries each with 5000 files in the previous version and V10 :

V 9 Index Size

V10 Index Size

Index size: 10.9 MB Index size: 34.6 MB

Is SharePoint VSS writer the only backup method to protect SharePoint farm?

The SharePoint VSS writer supports Content database and Search Service Applications backups. All other SharePoint components can be protected without the VSS writer. By default the Content databases are excluded from the SharePoint database backup operation. We recommend to use the SQL Server iDataAgent to back up the content databases.

After upgrading from V9 to V10, why am I unable to view database backups during browse and restore?

In order to browse through the data that was backed up in V9, specify the End Time (which is a date /time before the completion of upgrade) in the Restore Options window. For details see, Browse and Restore Data before a Specified Backup Time.

Is Microsoft Office Project Server 2013 protected by the SharePoint Server Agent?

Yes, you can backup and restore Microsoft Office Project Server 2013 using the SharePoint Farm subclient.

To back up Project Server 2013, configure a Farm subclient and backup the following components:

  • Project Server service application and associated proxy service
  • Web application and content database of the Project Server service application instance

To restore Project Server 2013, restore the above mentioned backed up components from the Farm subclient.

After running a restore operation, add users to the user policy of the associated web application of Project Server service application instance. If not added, users will not be able to access Project Server service application instance.

Is Microsoft SharePoint 2013 Apps protected by the SharePoint Server Agent?

Yes, you can backup and restore Microsoft SharePoint 2013 Apps using the SharePoint Document subclient.

To back up Microsoft SharePoint 2013 Apps, configure a SharePoint Document subclient with web or a higher level data as content (like site collection or web application).

In case of Apps with user data, only those that use a SharePoint list internally are protected, else only the app is protected. For restoring the data, select both SharePoint Apps and the corresponding SharePoint list.

How do I prevent ASPX and Master Page errors during a restore?

To prevent such errors, create the additional setting dImportRetainObjectIdentity with a value of 0.

  1. From the CommCell Browser, navigate to Client Computers.
  2. Right-click the <Client> and then click Properties.
  3. On the Client Computer Properties dialog box, click Advanced.
  4. Click the Additional Settings tab.
  5. Click Add.
  6. In the Name box, type dImportRetainObjectIdentity.
  7. The Category and Type details will be automatically populated.
  8. Alternatively, you can click Lookup and search for the additional setting using the Find box.
  9. In the Value field, enter 0.
  10. Click OK.
  11. Restart the services on the client computer.

Can I restore list items to a different list?

List items can only be restored to Lists of the same type. Restore of a List may fail if restored to a site that does not have that list template type. For example, some Meeting Workspaces have lists that are specific to the Meeting Workspace, so these cannot be restored to a Document Workspace or a Team Site. List template keywords from Knowledge Base site might not exist on Non-English setup.

Is SharePoint DB restore of configuration database and content database of the central administration supported?

Yes, you can restore configuration database and content database of the central administration using the SharePoint agent. These components are restored in the SQL restore phase of the restore operation. However, we skip restoring these components in the SharePoint restore phase of the restore operation.

When is CVSPDatamigrator database created and what does it contain?

CVSPDatamigrator database is created when you install RBS on your setup. In the CVSPDatamigrator database, you can find the RBS configuration details such as RBS front end web server details, user information and content management schedules like data migrator schedule and RBS maintainer schedule. It is always a best practice to back up CVSPDatamigrator database. The size of this database is very small around 20 MB so there is no need to truncate the transaction logs.
