Why does backup software not simply copy files as they are?

I have a few Seagate external HDs.  Previously, I had other discs (that failed!) but these  seem quite good.

 

They come with a Seagate backup management system that you run - it wanders off and makes a backup of your PC/Laptop and promises that it will be available for restore if you need it.

 

My experience, admittedly some years ago, was that these proprietary systems make a sort of encrypted backup which requires their systems to restore.  No software, no restore.  My B-I-L had exactly that problem last year.  Backed up using some particular software and when he needed to restore, got some computer speak for "not possible"

 

What I've done with my current externals (one in my home country, one here on the boat) is copy my photos, my music and documents from the laptop to the Drive, file by file.  This is irritating when I want to refresh the back up because all I want to do is save the changes across, not the bulk of the originals.

 

Why do all these programs insist on backing up in some obscure code format and not simply file-to-file.  If it was file-to-file, I could go get a file I accidentally deleted etc.

 

Why make things complicated?  Or is there a $$$ issue here I am missing?

When they perform a backup they are compressing the files to save on storage space on the backup drive.

Also when they perform incremental backups, they are only backing up differences between files that have changed and not the entire file. This saves considerable time and space when performing the backups.

Had a similar experience many years ago. Was running a backup after a very long time without one using Acronis and about an hour into the game, the drive died in the laptop.

I was hoping the target drive still has something useful, but no! Even though it had backed things up, I couldn't use them, everything was lost because it didn't finish!

That experience made me a firm believer in file backup software. At work we use CommVault and BackupChain for different environments and pay close attention to the container file issue. It's OK as Lawrence writes when you make full image backups of your hard drives, but when you have critical business data, most users prefer to have both files and disk images.

Ideally we try to use different software and independent media for the same data.

My colleague argued, to top our paranoia we now must "back up to the cloud" soon.... Don't know about that one, thinking about our slow internet lines, sounds too futuristic for now....

The restore issue is also a good argument. I think most vendors do indeed make a $$$ issue out of it. Then the question arises how are you going to restore a 20 year old backup when the product no longer exists? Hence, we always want files directly accessible for archives...

I see Grinler has answered your main query.  However, if you are copying your changes across manually then that's not a very efficient way of doing things - especially so if there are lots of changes scattered across several directories/folders.  What you need is synchronization software.  There are many such programs, but here are a few:

I'm actually using Toucan on Windows 8.1 without any issues.

Thanks for that info.  I've looked at the three mentioned and as what you would call an enthusiastic amateur I like the look of FreeFileSync.  I will explore all three, though.

 

Thanks for all the helpful advice.

 

I have another open question over in Android OS if anyone cares to offer a suggestion on the second question I asked in that post re a new tablet.  Samsung compartmentalise their "Service" and won't deal with tabs bought outside their own little silos.  Since I bought mine in Greece (I just happened to be walking past the big electronics chain there and saw it advertised in the window), Australia refuses to look at it.  My fault, I broke my golden rule about not having any Samsung products)

I looked at the three backup utilities in depth and selected FreeFileSync.  Ran it yesterday for the first time - worked well.  Will put it on Laptop #2 in a day or so.

 

Thanks for the advice.
