New Server Contractors

Tom Marsh from the Higher Education Funding Council ( has been addressing the continuing problems with data redundancy on several LEA servers. As we know the core infrastructure we implement provides several robust techniques for data duplication specifically to avoid data loss, but as we all also know, there are instances when for one reason or another, data is not backed up.

One such instance that has raised my hackles lately is that of an HP server in a local school. Several of you who know me personally will immediately know the school I am talking about but I’m not about to start naming names and pointing fingers of blame. The data loss happened, it wasn’t backed up and that was the situation we had to sort out.

In an effort to streamline our go-to contractors I’m moving our server support to the people below. I’ve used them three times now and unlike some other recovery companies I’ve had experience in dealing with, this lot are actually pretty good and seem to know what they are doing. Contact me for names etc if you need them, I now have some very good techie contacts.

RAID 5 Data Solutions

For those of you thinking about using a RAID server system to store school / college data here’s an article I just found. Best, Jan.

For most of companies of all sizes, access and data storage is quite critical for the progress of the organization. Each year, the number of data being processed by companies is greatly growing making it more and more crucial to have systems set up to manage those data loads. A Redundant Array of Independent Disks (RAID) is a perfect option for several businesses that process lots of data and data, however there are lots of kinds of RAID to select from. This article will concentrate on the uses and advantages of RAID 5, and can also highlight possible scenarios for failure.

What’s RAID?
Essentially a RAID is really a software and hardware system which enables computer data to be written to multiple hard-drives.

The most typical terms used for every degree’s perform are “striping” and “mirroring”, with both executing different capabilities. Striping however is the purpose of creating one file to multiple hard-drives in little bits. In case you had 2 drives within the array, a file could be created for both drives and split in two. This allows for extremely fast write speed, however in its fundamental form doesn’t provide protection against redundancy.

What’s RAID 5?
This special kind uses striping to enhance read operation but also provides redundancy and fault-tolerance in the event of the disk failure. This is accomplished with parity data stored across the disks within the array; if one disc fails it can be reconstructed with the data stored in the other-devices. A RAID 5 system will optimize using storage space, since there isn’t any big number of data reflected across multiple devices, which has significant advantages.

Benefits Of RAID 5 For A School / College
1) Quick read speed
2) Protection against disk failure

The quick read speed makes this technique perfect for data archiving methods and any business place that accesses particular info on a quite regular basis. Nevertheless, write speed because the additional parity data must be created, is decreased when compared with other RAIDs also because the data. Nevertheless, you really need to be mindful of potential system failures.

RAID 5 Failures
The machine switches into a crucial mode where writing and reading remains achievable, but in a greatly diminished rate if one drive in the array fails then. It is rather crucial that prompt action is taken to reconstruct the array and replace a drive. If more than one drive within the array should fail failure to fix the system could result in damaging problems. At that phase you’d be looking at considerable costs in an attempt to regain a number of the data, with-there being potential for loss of data. It is significant to notice that while RAID 5 does supply a particular degree of redundancy it’s no replacement for back-up systems. For failures on these type of system it’s necessary to get outside assistance as our internal IT people don’t want to touch these. Recommended link here.

Then RAID 5 is likely among the top options and also the speed of having the ability to get that data is crucial to the progress of the business if your own business processes lots of data you’ll be able to choose. It’s some degree of built-in protection as explained above, and you’ll find a considerable rise in the pace at which information can be accessed by your systems.

Warning – MacBook Air Drive Failure

Run the Apple diagnostic to see if your Macbook Air’s are ok. If not they’ll need to be swapped out.

Apple have issued a recall notice on some Macbook Air computers manufactured in early 2013 due to hard drive failure.

Yes, yes I know all our staff should back their data up but we can all guarantee more or less every week a call from a member of the teaching faculty (usually chemistry…?) about lost data.

There’s an Apple knowledgebase article about the problem and an Apple download that will check if the hard drive is a faulty one too.

Recovering Data from Damaged Storage Tapes

In this post we’ll look at recovering data from a damaged storage tape, the various kinds of data case repair and recovery services available, and how to proceed when you have difficulties reading the data from your data back-up tapes.¬†As a kind of data back-up many businesses and organisations still use tapes. Their longevity is because of their simplicity of application and the number of data they could keep, even though tapes are believed to be old technology by many.

LTO is really a storage system which is created by Hewlett- Packard and IBM. If it occurs it is needed to splice the tape end straight back together – many problem is caused by this of course once the tape is read and also the data is then our of sequence. Some low level programing is crucial as a way to get for this data issue and successfully recover and read data from the cassette.

Using a DLT system now means the speed it provides and also you can store as much as 110 gigabytes on a tape is 10 megabytes in a second. The DLT tapes have been enabled by this latest advancement to defend myself against systems and networks that it might not formerly manage.

DLT (digital linear tape) is really a system that’s existed since 1985 recently this system has experienced an improvement in speed and capacity which makes it a desired storage system. Should you need storage for the small or moderate type system it will be wise to utilize a DLT storage tape. DLT tapes are a dependable means to keep your systems as it runs on the straight upward and down record kind mode. DLT has got the capability to see and regain tapes that you’ll have that are old however it’ll be unable to to create them. You’d be advised to keep your current archives in a format that’ll enable the DLT system to utilize them. In regards to rerecording your older tapes onto new ones this technique can help you save on time and cash.

Both LTO and DLT systems can provide you with a quick and powerful approach to keep your backup files. No matter how the popularity within both systems undoubtedly leans towards making use of the DLT system. Broken tapes can frequently be fixed as well as their data recovered by skilled cassette recovery businesses. Over thirty million cartridges are sold to date meaning the product is undoubtedly a popular among individuals searching for a powerful approach to back up their systems.

Now you can use an even more complex system for example DLT to re record and put your storage onto an even more powerful means of saving for those who have used a DDS system previously for storage functions.

On tapes you might be keeping storage is an amazing way to guard your assets that need storage options, this can shelter you from damage and permanent loss. Make sure to constantly put data onto a back-up system to avert losses which can be experienced from stealing or damage.

Now the demands on storage have become to new heights and more and more folks are considering options available on straight back up, retrieving, saving and shielding of significant data.

LTO offers new technology together with a higher powered manner of burning of your own data, while DTO offers a refinement to you within their new Super DLT range which has come leaps and bounds from the initial system used before.

Data Security and Privacy

Following on from my mention of the dom-i-nate web site I’ve found another new one that looks like it may have interesting comment and analysis on all matters data security and privacy related. Its, and although there’s only been 1 post so far, it’s about CCTV and DVR video technology and suveillance. It’s suggesting that in this day and age it’s more and more difficult to do anything in a public place without it being recorded (and monitored?) somewhere. Infact we all know that what we type and send across the internet gets intercepted and trawled for various keywords and phrases that might suggest a terror plot of some sort. Just by typing in words like assassinate and bomb increase the possibilities of a post like this being red flagged and interrogated further… So hello to everyone at the NSA and GCHQ who may be reading this.
