Backing up to a network share is just as easy as backing up to a local volume. The significant difference is that it can't create a Volume Shadow Copy Service snapshot of the remote volume. Therefore, each full backup will overwrite the previous, leaving you with just the latest full backup image of each server on a network share. Due to this limitation, you can't use the Windows Server Backup scheduler to schedule backups to a network share. You can, however, use the Windows Task Scheduler to run the WBADMIN command-line program to perform full backups to a network share. If you elect to schedule full backups to a network share this way, change the target folder for each backup to avoid overwriting previous backups.
Asi tedy budes muset pouzit:
wbadmin start backup -backuptarget:\\server\share -allcritical -vsscopy -user:username -password:password -quiet

P.S. 2008R2 sice upozorni ze scheduled backup na sit nema smysl jelikoz se hobluje neustale pres sebe ale necha jej vytvorit
