Cambridge based Backupify has just raised another $9 million in series C funding. The round was led by Symantec Corp and includes participation from existing investors Avalon Ventures, General Catalyst Partners and Lowercase Capital. The backup provider has now raised a total of $19.5 million.

Backupify offers an all-in-one backup solution that allows you to archive, search and restore files for the most popular online services including Google Apps, Salesforce, Facebook, Twitter and more. The company was founded three years ago and since then has safeguarded data for more than 5,000 business, backing up more than 300 terabytes of data including more than two billion emails.

“Every day the CIOs and I.T. leaders we talk to are asking us to support more of the cloud-based applications they use to run their businesses. This new round of funding will enable us to extend our market leadership by adding more features and products to fuel new customer adoption, and help businesses move to the cloud with confidence,” said Rob May, CEO, Backupify. “We’re excited to have Symantec involved in this investment, validating our strategic vision to drive innovation in cloud data management and backup.”

“As more data is stored in cloud-based services, the threats to that data posed by user error, corruption and hacking also increase. Maintaining a secure second copy of cloud-based data can mitigate each of these risks,” said Anthony Woolf, senior director, corporate development, Symantec. “We support Backupify’s efforts to help consumers and businesses protect the data they create in cloud applications.”

It will be interesting to see where the Symantec relationship goes. A security provider investing in a backup provider makes sense, but something tells me that we’ll see a lot more collaboration between the two.
