already discussed a full backup of the computer in this article:
however, treat the data backup and precisely which programs to use and
which devices will direct our choice based on possible needs that may
Before starting I would like once again the importance of backups not just in office but also at home. In
fact, just think that by now most users store their photos on the
computer without thinking about a possible failure of the latter.
Moreover, even if aware of this think that the possibility of a taste is very remote.
reality, the hard drive failures are the most common because they are
the first to feel the wear of time and data recovery can become very
difficult and expensive if not impossible.
To back up the data there are several methods and / or applications.
backup can be done manually by copying the new folders on the computer
also added on the external device or use applications appropriate for
this type of task.
Obviously the choice is very
wide and also price differences, we start from the professional ones,
with about 800 € to finish in the free ones for home use.
free of charge is less reliable than those that are professional but
have different features and functionality from your professional
services (eg at home can do without an encryption of files stored),
hereinafter set before you a list of freeware programs tested starting from the best:
- GFI Backup
- Macrium Reflect Free
As for external devices such use should reflect the data that you want to store. Many
people, having these devices a high capacity, I insert all the data on
it and not on the computer then the security of the backup in this
manner is less.
Some devices also
address this problem because they contain within it more hard drives and
RAID system based on the data is replicated or not.
the first characteristic to consider for your device and if you have
multiple hard drives in the external device, the cost of the equipment
currently is around 250 €.
The second feature to consider is certainly the communication system which determines the transmission speed and ease of use. The
best transmission speed can now be obtained using the USB 3 port (which
should be available on both the device and the computer) or via a
network port (the device in this case is called NAS).
feature that ultimately distinguishes the external storage devices is
the ability to provide data running player also features a video /
audio, it is possible to connect devices such as televisions or iPhone
to view movies, photos and songs the backup device.
