Backups Using too much disk space

I've got Norton Security with Backup Premium.  I use the backup to save files to a network drive.  The problem is that I've now got 200GB of space used on the backup drive for less than 100GB of used space on the drive being backed up.  Why does it need twice as much space on the backup drive as the files being backed up?  Is it just copying the files over any time they change without deleting the old versions?  If this is so, how do I control it?  Is there some way to switch back and forth between backup sets or something so I can purge the old stuff?  I don't understand why its using so much space.

Re: Backups Using too much disk space

Good Question looks like they just want to sell more storage space. No need for it, funny way to treat your customers !

Re: Backups Using too much disk space

Whatever the issue is I don't know it. But thinking the reason could be the one advanced by db133 is just outlandish... MAT_Blue, as I understand, is using a local network drive for his backups!

I don't use NSBU for my backups (I use Acronis) and I always do full backups, not incremental or differential backups as it seems to be the case here. It's well known that the incremental backups and especially the differential ones end up as larger backup files, depending on activity, but still, I do agree that something doesn't look right here.

Good luck.

Re: Backups Using too much disk space

Actually, I tend to believe db133 even though it seems outlandish.  How many people out there even understand how much space they're using and how much a backup should require.  You get 25GB of "free" online space with Norton Security but how many people are paying for two or three times as much as they really need because of how it works?  Not me.
BTW - I figured out how to switch between backup sets (manually) and delete the old set (also manually).  Still haven't figured out how to make Norton do it.  I'll probably switch to a different backup/security vendor when this subscription runs out unless I can get a reasonable answer out of Norton/Symantec but I really don't think they care.

Re: Backups Using too much disk space

Hi MAT_Blue.

Sorry to have been slow in responding to your query but I have been away for a while.

Without a lot of investigation which in any case I could not do at a distance I cannot say why all that space is being used, but I can make a guess based on experience.  Often in the past I and others have found that when you go to run an incremental backup the software can run a complete new backup and add it to the old one.  So if the original full backup was 100 MB and you had just added one file, the new file size would not be 100.1 MB but 200 MB.  This does appear to be a fault but as far as I can find out no one has yet managed to work out what causes the system to trip like this and such errors appear rare these days.  The "solution" in my view, is to create a new backup and delete the old overly large one that is doing you no good.  With this in mind I always run two identiacl backups with Norton, aiming to run them alternately.  Then if either of them start to expand too much I have the other to fall back upon until I can recreate the faulty one.

I hope the above is clear and helps you somewhat.  If you would like me t attempt any further explanation just say so.

Re: Backups Using too much disk space

It sounds like your solution is to set it up so I use twice as much space as I need (since I'll have two backups running alternately) and if the total size gets to be three times as much as I need, to delete one of them?  That doesn't sound like much of a workaround.  After all the years that Norton has been making backup software, I would think it would be a very high priority to fix such a glaring error.  If I was paying them for twice as much online space as I really needed because of an unfixed bug in their software, I'd be thinking "Class Action Suit."
As it is, I'm thinking, "dump Norton and go with a competitor."

Re: Backups Using too much disk space

Hello again MAT_Blue.

I am not saying that the error is frequent.  I am not saying that you have to run both backups to the same place.  

All I was suggesting was a possible way to allow for a problem with a backup set to ensure that you will be safe.  Any backup can go wrong, having a spare is an extra bit of insurance.

Another approach might be to watch and see if the backup file appeared to be growing to much and if so delete it and start afresh.  This would leave you at risk for a short while (until the new backup ran) but the chances of you needing the backup just at that point in time are probably small.

Sorry you feel so aggrieved with Norton.  As just a user of their product who tries to help other users, I have a feeling that Norton is not perfect, but what company is?  However I also feel that they have some fairly reliable products and some well intentioned staff, which is why I continue to use their products and try to help out here.  If you wish to move on to something else you are free to do so.

Good luck for the future and do let us know if there is anything else that you think I or other users may be able to help you with.

Re: Backups Using too much disk space

I understand you're a user trying to help other users.  How do I get this information to Norton/Symantec so they can fix the problem?  I was assuming they would be following the forum and responding to customers.

Re: Backups Using too much disk space

Hello again MAT_Blue.

If the problem you want them to fix is the one about backup size increasing substantially with no obvious reason, then I believe they are aware of it.  As to what will happen ... time only will tell.  But it does not seem to happen very often these days.
