Difference between STSADM Backup/Restore and Import/Export

I have been asked by many about the differences between Backup/Restore vs. Import/Export operations, they both really serve very different purpose.

Backup/Restore


Can back up top-level websites (Site Collections), an individual database, a Web application, or an entire farm.

There is no Default File Extension for back up files

Supports “Full” and “Differential” back up. If “overwrite” option is selected while restoring it overwrites entire SiteCollection

Supports UNC path to save/restore backup files.

Backup of Site Collection can be tracked by stsadm -o backuphistory operation

Import/Export

Like Smigrate.exe utility in SPS 2003, you can migrate sites, subsites and Site Collection.

Default file Extension (if not mentioned) “.cmp”


Provides “versions” option to control migrate/overwrite files in site

Backup files should be copied to server

Sites/SiteCollections would not track export/Import history

Syntax

stsadm -o backup
-directory
-backupmethod
[-item]
[-percentage]
[-backupthreads]
[-showtree]
[-quiet]

stsadm -o restore
-directory
-restoremethod
[-backupid]
[-item]
[-percentage]
[-showtree]
[-suppressprompt]
[-username]
[-password]
[-newdatabaseserver]
[-quiet]

stsadm -o export
-url
-filename
[-overwrite]
[-includeusersecurity]
[-haltonwarning]
[-haltonfatalerror]
[-nologfile]
[-versions] <1-4>
[-cabsize]
[-nofilecompression]
[-quiet]

stsadm -o import
-url
-filename
[-includeusersecurity]
[-haltonwarning]
[-haltonfatalerror]
[-nologfile]
[-updateversions] <1-3>
[-nofilecompression]
[-quiet]

Changing Content Type Hub URL

Change the Hub URL through powershell by using: Set-SPMetadataServiceApplication -Identity " " -HubURI " " For Ex: Set-SPMetadataServiceApplication -Identity "Managed Metadata Service" -HubURI "http://contenttype.Domain.Com" When you try to do this you get this rather scary message: This is SharePoint telling you that this is a major thing so be careful! Essentially all your content types that you have published out will be removed if they can, and you have to republish all of your content types out again which can cause some issue.
