, this is the core challenge of NAS backup, and the network performance of the NAS is uneven. Q: Is ndmp a good choice for NAS backup? How does it work? Answer: NDMP was introduced to the industry about 10 years ago. That's when NetApp started to become active, and NetApp NAS devices are the kind of equipment that you can back up with headaches. Then people would ask, "How exactly do you back it up?"
VSC is a plug-in that NetApp stores on vsphere vcenter 4 and is not a vsphere client plug-in, so it must be installed on vcenter. After installation and then login vcenter, there is a NetApp tab in the Datastore view.
With VSC you can easily access NetApp storage and scan the ESX datastore on NetApp storage, whether i
a viable option, but applications such as databases directly choose to use logical volumes to implement snapshots because they cannot be managed by snapshot technology at the file system level. In general, there is no need to implement snapshots at the application layer, which can be implemented using the underlying file system or volume Manager interface for backup mechanisms, but requires a temporary pause to ensure snapshot data consistency. In general, software-layer-based snapshots are eas

For devices that support mobile storage (such as USB flash drives, SD cards, and CF cards), I think Autorun technology is a very powerful method. Then, it runs. It is very simple but practical, similar to the CD/DVD Autorun technology. Windows Mobile directly supports Autorun. In fact, it is easy to implement on Windows CE: runtime runs.
To implement this function, you must first create a message queue during initialization to wait for the system device plugging time notification:Code
