NEW TUTORIAL Continuous
data protection backup products tutorial
Many people viewed continuous data protection as the Star Trek of the backup industry -- a great idea before its time. Star Trek, maybe not fully understood when it first aired, was canceled after three seasons. Similarly, many people thought continuous data protection was a solution looking for a problem, and most shops could meet their backup and recovery requirements without completely changing the way they did backups, which was required with CDP. Learn about CDP backup products, near-CDP vs. real-CDP and more in this tutorial.
When discussing snapshot-based backup systems, there are a number of misconceptions that must be dealt with before beginning the conversation. Learn about the pros and cons of replacing your traditional backup system with snapshot backups in Curtis' latest column.
virtual machine backup with image-level backups, CDP and near-CDP
It's time for users to pull their heads out of the sand regarding virtual machine (VM) backups. Server virtualization software such as VMware or Microsoft Hyper-V may solve a lot of problems for system administrators, but they create a lot of problems for storage and backup administrators. Learn how to simplify virtual machine backup with image-level backups, CDP and near-CDP in this column.
backup and desktop backup best practices
Laptop data backup and desktop data backup is just as important as enterprise data backup. Whether your laptops and desktops are for business or personal use, you want to make sure they're backed up correctly because the data on them is often more vulnerable than data that is backed up on a server storage system. Learn best practices for backing up laptops in this podcast.
NAS backup challenges
Network-attached storage (NAS) backup can be a challenge for many data storage administrators because in order to back up data, it has to be sent to a backup server across the network. It requires backup agents installed on servers to access storage on a NAS device, and it can be inefficient. Other technologies exist to simplify NAS backups such as Network Data Management Protocol (NDMP) and near-continuous data protection (CDP), but do these technologies have limitations as well?
