Disadvantages of local backup options contain the undeniable fact that in the event your building suffers a disaster, for instance, burning to the earth, your copies choose it. The single greatest benefit of remote data back-up solutions is the fact that they are, properly, remote. This means it is virtually a "set and forget" proposition. When the software is set up, the copies are done automatically, without human intervention.
There is, in addition the advantage of protection with remote back-up options. Startup costs are insignificant, and as your conditions for file hosting grow, for comparatively little additional expense, your storage space grows with it.
The main drawback of on-line distant backups is speed. Uplink speed for many web users is significantly below downlink speed, and big copies can tie-up the uplink for considerable quantities of time, restricting bandwidth availibility for other applications.
Overall, I believe I had still pick the remote data backup within the onsite backup, just for that cause of data protection. I love the thought that my information is secure and protected in a different place, and will also be kept current with almost no human intervention from me.
