Not enough room for bu????


I have scheduled a bu on saturday. After some time I got an error something like 'not enough room for bu'. The bu disk (the one I want to bu to) is 500 GB of which appears 305 is 'used' and 160 GB is free. The bu takes 146 GB. I see an information code 4138 but don't see it in the list of error codes.

Any suggestions??

  • You mean the size of backup file is 146GB?
  • Thanks for your help. Yes it is.

    How do you know it takes 146 GB? That number could be correct but you know it only after the backup has completed.
    I think Aomei has to make a guess upfront because the actual amount is only known after the backup and after the compression (depends on many things) and decided that 160 GB is not enough.
  • 1. I checked the properties of the bu on my hard disk and that is 146 GB.
    2. I checked the folders (3) I wanted to bu and together they are 206,7 GB.

    By the way , I tried to clone my computer onto a harddisk (1 TB) and it was stopped because there was not enough space fot the bu which is, according to AOMEI 432.. GB.

    Very confusing.

    Maybe I should format the hd's and start all over again.

    I think it means the backup was successfully done, then how did you encounter the 4138 error?
  • It was in the error dialogue box.... I think.
  • I googled for the meaning of the error but couldn't find it in the list of errors.
  • Not sure why but maybe you could try a larger disk.
  • Okay as long as it works a wild guess is as good as any guess, but.....

    First I am going to try the following: disconnect the hard drives, format them, reconnect them to the laptop and set up the backup again.

    By the way why should 146 GB indicate that the backup was completed?
