Solution: Command-Line backup tools – The stsadm.exe enables sharepoint admins to backup site collections using the command line and makes it easier to restore site collection (or a site).
stsadm –o backup –url <url> –filename <filename> [-override]
stsadm –o backup –url http://myserver/sites/ –filename c:\mybackups\
Catastrophic backup: The stsadm utility now lets you do a full SP backup as you would with a CA Page.
To issue a full or differential backup use the format
stsadm –o backup –directory <unc path> –backupmethod <full | differential> [-item<created path from tree>] [-%<int between 1 and 100>] [-backupthreads<int between 1 and 10>] [-showtree] [-quite]
for example: (to back up entire SP Farm)
stsadm –o backup – directly \\backups\sharepoint –backupmethod full
