Some Considerations Before Choosing A Data Protection Solution

Many network administrators are considering an all-in-one data protection solution because it can greatly simplify data protection process. These solutions also tend to be less expensive than buying each component separately, and they provide a single point of contact for all their support needs.

In a recent survey it was found that over half of the respondents indicated that they would prefer to rely on a single vendor for their data protection solutions whenever possible.

An all-in-one Data Protection solution the purposes of this article includes the hardware components and necessary backup software to backup an organization’s critical data, maintain the backup data both on-site and at secure off-site locations, monitor the system 24X7, provide server virtualization, and data restoration so the data network can be up and running as soon as possible.

There are a few things to consider before making a decision about going with a particular data protection solution.

1. What software is included?

There is client software loaded on the server for the backup process. The resident NAS software is used for compression, encryption, bare-metal recovery, and continuous data protection.

2. What type of hardware is being used?

A network attached storage (NAS) server with internal storage capacity is attached to the network and the server hard drive is mirrored in the NAS storage.

3. Is the solution secure?

Most solutions offer encryption. Encryption is critical component in backup data protection. The solution should support AES-level encryption. The backup data should be encrypted on site and while in transit to the off-site location and at the hosted site.

4. Is offsite backup included in the solution?

Most companies today need not only onsite backup, but they also need the capability to have a redundant copy of their backup data stored off-site so the data can be recovered in the event their site was unusable. Both on-site storage and remote storage should be part of the solution.

5. Can the solution scale to data storage demands?

The data protection solution should be capable of running efficiently and scale without a lot of specialized hardware

6. How often is the data backed up?

The frequency of the data backup determines how much data will be lost. If the data is only backed up once a day then 24 hours of data will be lost. Most businesses could not accept that kind of loss. They require a shorter recovery point. Most solutions provide backups take place every 15 minutes. The best practice is to determine an acceptable recovery point and pick a solution that meets that objective.

There are a lot of all-in-one data protection solutions. Some companies prefer to purchase deploy, and maintain the solution themselves. An in-house also requires the labor and expertise to administer the system. Some solution providers bundle the data protection equipment and software into a bundle that also includes the labor to monitor the system 24X7 as well as the labor to maintain and respond to notifications and outages. The system should be flexible enough to scale as needs change and provide a one-point-of contact when there is a need for service.

Glossary of Hard Disk Drive Terminology (Letter Q)

Qualification
The process by which sample components are tested for their compatibility and utility as parts of a system. Western Digital OEM customers qualify WD hard drives for use in their computers.

Queue
A first-in-first-out (FIFO) data structure used to sequence multiple demands for a resource such as a printer, processor, or communications channel. The host adds objects to the end of the queue and takes them off the front.

Resolve O LBA, Seagate 7200.11 BIOS don’t recognize (Part II)

PART 2

If your HDD 7200.11 is not recognize by BIOS,

and after you connect him to COM1 and turn on power if you have this response for any command like:

Rst 0x10M
LED:000000CC FAddr:0025BF67
Ctrl + Z
F3 T>
LED:000000CC FAddr:0025BF67
your drive is busy!

power off your Hdd
slightly unscrew one screw near to motor connection to PCB and put plastic visit card! Or you can remove PCB.
Effect is the same…
power on your hdd,

Ctrl +Z

F3 T>/2
F3 2>
F3 2>Z

Spin Down Complete
Elapsed Time 0.138 msecs
F3 2>

now you put PCB back, or pull visit card
enter this
F3 2>U
Spin Up Complete
Elapsed Time 7.242 seconds
F3 2>

F3 T>/1
F3 1>N1
this is a S.M.A.R.T. erase

after that POWER off HDD, it means that you plug off power to hdd,
power on hdd,
reenter
CTRL+Z on terminal
F3 T>i4,1,22
this is G-list erase

after that POWER off HDD, it means that you plug off power to hdd,
reenter
CTRL+Z on terminal
F3 T>m0,2,2,0,0,0,0,22 Enter

!!!IMPORTANT, don’t turn hdd power off, or comp off, wait about 30 sec to 2 minutes until it finished!!!

then you see something like this.

Max Wr Retries = 00, Max Rd Retries = 00, Max ECC T-Level = 14, Max Certify Rewrite Retries = 00C8 Max retries Wr = 00, Max Rd retries = 00, Max T-ECC Level = 14, Max certify Rewrite retries = 00C8
User Partition Format 10% complete, Zone 00, Pass 00, LBA 00004339, ErrCode 00000080, Elapsed Time 0 mins 05 secs User Partition Format 10% complete, Zone 00, Pass 00, LBA 00004339, ErrCode 00000080, Elapsed Time 0 mins 05 secs
User Partition Format Successful – Elapsed Time 0 mins 05 secs User Partition Successful Format – Elapsed Time 0 mins 05 secs

After that hit

F3 T>/2
and
F3 2>Z
Spin Down Complete
Elapsed Time 3.038 msecs

Turn off power from your HDD, od shutdown your comp.

That’s all!

WARNING: Please do NOT try this if you have valuable data on your drive. Do not blame anyone if something goes wrong. You do it at your own risk. Remember that if something goes wrong, it is extremely unlikely that anyone will be able to help you remotely. One wrong command via terminal could easily result in a completely bricked HDD (I really do mean bricked = no one will be able to recover it, even Seagate).
