Challenges for "Go" NAS backup

, 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?"

Introduction to VSC 1.0

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

Overview of Snapshot (Snapshot) technology development

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

Display of file modification time on NFS File System

The file modification time on the NFS file system displays the problem of Solaris + NetApp storage. The user's home directory is placed on NetApp and mounted to the local through autofs. You can use ls-l to view the touch file in your home directory. The mtime (modify time) column only displays the year, month, and day, but not the time. $ Touch file $ ls-l file-rw-r -- 1 user 0 Aug 25 2009 file after waiti

Deploy the vmwarevsphere esxi server 5.5 environment on 6 new blades, and migrate the original system collected in step 2 to p2v.

Defects of online storage data compression technology

). With the duplicate data deletion technique, the data is not changed, but the copy data about 2-n times is deleted, and the indicator is inserted into a "main instance" of the data. A single instance can be treated as a duplicate data deletion. Traditional data deduplication is often not suitable for online software or primary storage software, because the algorithms needed to replicate data removal inevitably increase response time, which leads to increased costs. For example, popular de-dup

What Is Nas?

familiar with these protocols, you do not have to worry about them. We will discuss them in future articles. Of course, the NAS mentioned above cannot be sold. Most enterprises choose NAs from companies such as EMC and netapp because they have features that are hard to implement on common file servers. First, let's give a brief introduction.

Facebook's storage architecture needs to deal with two things: Read and write. We will observe separately. Write: When a user needs to upload a photo, that is, a write to the Facebook store, Facebook assigns an upload server to work. The upload server processes the uploaded photos, and each photo is stored according to the 4~5 s

VC project debugging Basics

debugging VC, the compiler can trace the C library function because the compiler itself provides the debug version of the CRT library. The MSVCRTD.DLL-MSVCRTD.LIB-MSVCRTD.PDB in vc6 (corresponding to msvcr80d. dll-msvcrtd.lib in vc2005) is the debug version of C Runtime Library, which contains the debugging information of C Runtime Library.
