First, let’s take a look at onsite backups. Clearly, the single greatest advantage that onsite backups have over remote data backup is speed. With LAN speeds of up to 1Gbit, and USB 2.0 clocking in at 400Mbps (with USB 3.0 and speeds of up to 4.8Gbps just starting to make it into some hardware), 聊天室 the ability to speedily backup your data to a network resource is the killer app for local backups.

Cost is also a benefit to small businesses of local backups. In a lot of cases, you might already have a networked drive somewhere on your LAN with plenty of free space 交友網站. If this is the case, the cost of setting up your local backup solution can be as little as zero. There’s also no ongoing cost associated with LAN based backups. Even if you do need to buy extra storage, it’s a one-off cost, without the monthly fees that accompany remote data backup solutions.

Disadvantages of local backup solutions include the fact that if your building suffers a catastrophe, for example, burning to the ground, your backups go with it 識男仔. Whilst you can take backups offsite, this is a two sided process; backups need to be copied onto a removable drive or optical media, then someone needs to actually be tasked with the job or remembering to take the data home each night.

Now to Online Backup solutions. The single greatest advantage of remote data backup solutions is that they are, well, remote. if something happens to your building, or you suffer a hardware failure, your data is sitting there on the remote server, ready for your glorious reunion when you’re ready to download it again.

Other advantages of remote data backups are that they can be performed persistently or on schedule. This means that it’s pretty much a “set and forget” proposition. Once the software has been set up, the backups are performed automatically, without human intervention.

There’s also the benefit of security with remote backup solutions. Data is encrypted both ways (client to server, and server to client), and good remote data backup providers have their own redundant backup network, meaning that your data is backed up across servers in different locations, so that if one datacentre suffers and outage or system failure, your data is still accessible via the other servers in their network.

Another advantage of online backups is that they are virtually infinitely scalable, and there is no initial hardware infrastructure outlay. Startup costs are negligible, and as your requirements for online storage grow, for relatively little extra investment, your storage space grows with it.

The major disadvantage of online remote backups is speed. Uplink speed for most internet users is significantly lower than downlink speed, and large backups can tie up the uplink for significant amounts of time, limiting bandwidth availibility for other applications.
