Question

Backup keeps running out of space??

Asked by: hardstarburst

I have 3 physical drives on my machine, 320gb each. C has XP, E has a bootable copy of XP and is where I store my backup. F has Vista.  I did a full backup of C (219gb) and stored it on e (backup file size is 192gb) So there is 97BGB left on E. I must be misunderstanding how a backup works, because I thought i'd be able to backup a drive with one that is the same size- especially since there is some compression used. Anyway, Whei I tell it to do the incremental, it runs out of space and fills up the 97gb or so of space left available on the backup drive e. I thought it was only supposed to contain new data since the last backup??  I haven't added 90Gb of data since then, I have norton set to keep only 1 base set of the backup, so I can't figure out why it would keep running out of space. I would understand is running out of space if it were trying to duplicate the drive contents again, but it's not ssupposed to be doing that. Any help on this would be appreciated.

The basic answer is that even though you ask Norton Ghost 14 to take an incremental backup, *if* enough or too many sectors have changed, Ghost (on it's own) decides that it must take a full image backup.  If you take incremental backups for example every night, and a weekly base backup, you would expect to have 6 small increments and 1 large on for any given time.  No.

Instead often during the week, you will see Ghost take another full image backup.

So, since you have to have room to successfully complete the backup operation before deleting an older generation, you must have enough room on your target (E in your case) for at least 2 full images.

How much USED spac is on c?  Using normal compression, the output should be about 50-60% of that.  Maybe you made a mistake or told Ghost to not use any compression, or disabled smart sector copying or something else.

Don't be confused by creating a backup-image-file of your partition vs. data cloning (one time operation when replacing a hard drive).  

You must have large databases or videos, music, etc because you c drive used seems way too big for normal operating system.

The status of the drives are shown in the bitmaps posted below. In having Norton set to make one base set and incrementals every 2 weeks, I thought  had more than enough space to do this. C takes up 213Gb (yes, there are years of accumulated files, music, video's etc. on there) and that is one big chunk out of E. But I have not added another 84.5 gb or more of new files in 2 weeks, so I don't understand why an incremental backup would be trying to consume more that 93Gb (free space available on the backup drive e)
You mentioned that "Instead often during the week, you will see Ghost take another full image backup." This has not occured, but is this something that you are seening in Ghost 14??
I guess  a more basic question that would help me get onto the right track here would be does one usually need to have double or triple the drive capacity than the amount of data they are backing up??

Info 6C8F1C2F: A recovery point operation on drive Drive Backup of Win_XP (C:\) was cancelled by the user. Error E0BB0083: Unable to create incremental image. Error E7D1001F: Unable to write to file. Error E7D1003C: There is not enough space. Error ED800013: Operation cancelled by user.
Details: The operation was canceled by the user.

Source: Norton Ghost

In theory, I could delete the recovery point set every 2 weeks and create a new one with the existing amount of space I have on my computer. But then I would be missing the point of having a program do this for me automatically. Seems to me i should be able to have a current backup copy of my drive given that i have like 98 more GB than i'm trying to back up.  Maybe Norton 14 is not the product me me??

First, thanks for the complete explanation and screenshots.  Very helpful.

>> does one usually need to have double or triple the drive capacity than the amount of data they are backing up??

Yes.  (I'm currently using Ghost 12, but I've used Ghost 9, 10 previously as well as older DriveImage predecessors of Ghost.)  Ghost xx needs to be able to have room for full backup even though you told it to only take an incremental.  

There have been many opinions, whitepapers, discussions, etc. on partitioning strategies.  Many/most of them encourage you to keep your c: operating system partition small (20-50gb) and separate your data from your programs.  Image backups are greate for recovering your XP or Vista pc after hard drive failure, but normal data backups are often easier done with programs such as www.goodsync or syncbackse etc etc.  There are many good data backup programs.

When you update a data backup group or partition, these programs are able to ONLY copy the changed files/folders, and keep them in native (or zipped) format.  Very convenient.

Having an external usb2 hard drive of say 500GB makes it easy to keep multiple copies of your c: partition (10-25gb each compressed).

Also, older video, music files, etc may not need to be backed up as often because many are part of people's collections of vacations etc.

Bottom line:  I would encourage you to rethink your separation of data vs XP in the partitions.  You can use Ghost for both if you want to, and still be automatic as to which partition images are created when.  Also, by keeping the XP partition small, you can even copy your backup-image-file off to dvd's if you choose to limit the chunk size of the images.  I do that and every couple months, burn a few dvd's and store them offsite.

Although I do not *like* the solution, I will accept it , because it will remedy the issue. I think Symantec should be made to include in the system requirements the fact that you need 3 times the storage space you are trying to back up to be able to get the full use of the product. Thanks for the effort, Xpert4XP

I think i'll just go back to Ghost 2003- it seemed to be simpler and works better..

 

by: Expert4XPPosted on 2008-03-21 at 11:00:38ID: 21181784

I agree, it's not real obvious about the output space requirements.  Buf if your normal C: partition is reasonable in size, then these 500 to 750 GB external hard drives will hold it.  The problem comes up when you have 500GB of video/movies/pictures etc.  In that case partition images don't make as much sense.  That may be why Symantec added the Folders/Files backup option.  That should be closer to what you want and an incremental version is just another folder, not the entire partition.

Glad to help, and I understand and appreciate your comments.
