1.4 Data protection challenges in the Virtualized Environment

Virtualized environments offer great advantages for shrinking cost, overhead and operational complexity. They also pose unique challenges for all sizes of companies including budgetary pressure, staff expertise, and changing data protection practices.

#1: Budgetary constraints. Even the largest companies are under financial pressure when it comes to data protection. Data is growing at dizzying rates, which bloats backup windows and increases data protection costs throughout the organization. Data growth also impacts IT by increasing its management responsibilities, even in the face of flat or shrinking headcount. IT expertise also comes into play. Enterprise customers will have specialized IT expertise but smaller mid-range and SMB will not.

#2: Inadequate traditional data protection. Traditional backup solutions tend to be oriented toward physical environments and, as such, might not be the most efficient approach for protecting virtual machines. While the task of packing virtual servers onto one physical server yields consolidation benefits, it also concentrates backup operations onto a single platform. This leads to overtaxed server resources.

#3: Proliferating backup. Typically with traditional backup, an agent resides on each server and backs up files on a predetermined schedule. If a restore is needed, the agent is used to recover the file, folder or email. In a virtual server environment, the actual virtual machine image is stored as a single file called a VMDK. The VMDK is different because it contains the operating system, application and files. Backing up operating systems and applications increases backup volumes, which in turn requires more capacity.

#4: VM sprawl. Once the initial virtualization stages are in place, it takes just a few mouse clicks to create a new server. However, this results in a proliferation of virtual machines, also known as VM sprawl. Each new virtual machine and its application data must be protected, which results in larger backups.

This challenging virtual environment presents these and other backup and data protection challenges and opportunities. New approaches integrate relationships between virtual application business continuity and recovery tools and the data protection stack of array-based tools.

Representative APR 391%

Let's say you want to borrow $100 for two week. Lender can charge you $15 for borrowing $100 for two weeks. You will need to return $115 to the lender at the end of 2 weeks. The cost of the $100 loan is a $15 finance charge and an annual percentage rate of 391 percent. If you decide to roll over the loan for another two weeks, lender can charge you another $15. If you roll-over the loan three times, the finance charge would climb to $60 to borrow the $100.

Implications of Non-payment: Some lenders in our network may automatically roll over your existing loan for another two weeks if you don't pay back the loan on time. Fees for renewing the loan range from lender to lender. Most of the time these fees equal the fees you paid to get the initial payday loan. We ask lenders in our network to follow legal and ethical collection practices set by industry associations and government agencies. Non-payment of a payday loan might negatively effect your credit history.
