I'm looking for recommendations for a backup plan for a company with 20 offices scattered around the country. We also have roughly 15 servers in our main office. Currently we use Commvault to run nightly incremental backups to our head office. But the backup jobs don't complete in time. Eg. 4 branches backing up at the same time, our two 2MB leased lines can't process them all quickly enough.
All suggestions appreciated.
