No backups? Don’t get surprised and prevent crying!
Big companies don’t need to be hammered on the importance of making good backups. They arrange this well. Sometimes it is not done perfectly regarding scheduling or security but at least the backup is running every day.
In little companies I see lack of good backups. They never check if the backup actually runs or is usable. Cutting costs on good maintenance is the issue.
I want to focus today on the normal computer home user. 10 years ago a home user had nothing important to do with backups. Occasionally a document and that was it.
Nowadays it’s different. Most families have at least 2 computers or notebooks in their home while this number is higher when they have more children in their family.
They all have their own passwords, documents, etc… but what do they backup at the moment?
In real life I see that they DON’T backup. They backup NOTHING. That surprised me a lot. People have the idea that harddrive will never fail and always will work. They don’t think about the possibility they can stop working in a second.
The photo and video files they have are GBs on data. I even know some families where they already have TBs on data. I have at the moment 5 TB on video (FullHD videocamera) and photo files. A good friend of me even has 16 TB on data and he told me recently it’s almost full. How are you suppost to backup this? What can you do as home user or little company?
The most easy solution is buying an external harddrive. A 2 TB external USB harddrive costs around 100 euro. Not expensive if you ask me. Harddrives have weakspots. If you really have important data I would recommend you buy 2. Maybe for your situation 2 x 1 TB is a safer option than buying one 2 TB. Be aware that 2 x 1 TB will cost more than one 2 TB.
If you buy an extra large internal harddrive you can also consider mirroring. When one harddrive fails the other takes over the operation. Disadvantage is that notebooks in most case don’t give you the possibility to add an additional harddrive, this solution can only be applied on normal desktop computers.
You can consider to buy a NAS (Network Attached Storage) solution. With a NAS you can connect harddrives to your network. Most of the NAS solutions offer RAID, RAID is necessary to do mirroring, like mentioned earlier. A NAS solution can be bought for 100 euro.
You can archive photos on a DVD. A single layer DVD can hold 4.5GB which are a lot of photos, a dual layer can hold even 9GB. Video files archiving is more complex. Especially if you use a videocamera which records in FullHD. You will notice the many GBs are used for recordings. You will have to archive those files on a harddrive. You can consider a Bluray writer (25/50 GB), but the GB cost is expensive.
If you really want to archive everything good you have to think about a tapestreamer. Be aware with large capacities they are expensive.
Take care of archiving you most important documents, photos and video file. Edit and publish on DVD your most important videos as soon as possible. Making a copie of a DVD is easily and fast done.
World of versions…
World of versions…
How are normal users able to know which are the possibilities and impossibilities of the devices and applications they use on a daily basis. Not to mention want to buy.
For me it started in the 90′s… U.S. Robotics had a modem on the market which gave the users the option to run a firmware upgrade so features could be added. Short after the first features even new speeds were possible via upgrading. Now this is more common than you can imagine. Almost all devices have some kind of upgrade system.
The reason for this is that manufacturers can release their products faster on the market. They can correct minor mistakes, often called bugs, or even add new features. Nowadays updates are also more published in the news because many times a new version implies a solution for a security issue.
Here are some examples of devices :
- Television (Sony v1.730EA)
- Mobile phone (My Sony Ericsson X1 runs Christian’s ROM version 5.721 with SPB Home Shell version 3.5.5)
- Tablet (Apple iPad version 3.2.1)
- Multimedia player (Playon!HD Mini, beta v7.00.21r4312)
- Playstation 3 (version 3.31, since a while 3D support)
The TV can now since the upgrade support CI+ modules which my cable provider Ziggo uses without the need to purchase a new TV. My mobile phone is more than 1.5 years old but thanks to the new ROM upgrade it has the newest applications and features like the modern phones have. My tablet is able to connect to newer WiFi networks since the upgrade and applications are running faster. The multimedia player supports new video formats. My PS3 can now play 3D games, twitter and Facebook without the need to buy a new console.
Ofcourse there is a limit on the new features. On a certain moment the device will hits its limit. It can not process the data fast enough, then it’s time to replace the device. Upgrading does lengthen the life span of your device, not doubt about that.
If you compare versions in applications you can see it’s a real mess. Maybe you are surfing via Microsoft Internet Explorer 8.0 or FireFox 3.0, this website is currently running on 3.0.1 of WordPress and I can continue for hours and hours. Techies can keep track of this, but normal users can’t. A worse administrator doesn’t do it. Companies with this kind of administrators are often victim of hackers, hackers use a lot of time the known security holes of old versions of software, they call them exploits.
