As mentioned yesterday. The soft/digital format of our data is growing and the level of backup in hardcopy is fast becoming scarce. As such redundancy in soft/digital format is becoming more and more important.
Today the most common method is people making another copy of the same on the same harddisk. For those fortunate to have corporate resources on their company server.
Other methods also are burning cd/dvd(a more permanent format but has its possible failings, see more in the future on this method), Thumbdrive (we will explore this further in later parts), external Hdd and now the NAS (network access storage). This is fast coming a more apparent good choice for most situations if employed properly.
Stay tuned for our next post where we will discuss the NAS further with the ensuing further post with all the other methods in more details.
