Backing up small files with BE 2012

I have to backup a servers with a a lot of small files. As expected the backup speed is very slow when backing up such files. I would like some suggestion on how to improve the backup speed of these type of files. Right now the backup speed for that server is about 105 MB/min. So it takes more than 2 days to do a full backup of less than 1TB, and it is becoming an issue because by the time the backup is completed the data is already old.

I've thought about synthetic backups, but I will need to buy the Enterprise Server Option license for that, and I'm not sure if this is going to work well since I've never tried with any BE version. And symantec no longer lets you try it free.

I'll really appreciate any sugestions.

Thanks
