Problems with fixed size splitting

Thread needs solution

I want to split my tib backup into DVD sized pieces.
So, I specify 4.7gb in the "tools>options>default backup options>archive splitting>fixed" to 4.7gb by selecting the appropriate choice. When the backup runs it does not split the file but makes one of about 12gb. Moreover when I return to the default settings again it displays 4.34gb. Any idea what' up with that???

Thanks,
Chuck

Hello Charles,

Thank you for using  Acronis Products

In order to solve the issue download and install SnapAPI drivers using the following link

I would also recommend you to check the hard drive for file system errors.

- Go to the Command Prompt (Start -> Run -> cmd)

- Enter the command: "chkdsk DISK: /r" (where DISK is the partition letter you need to check) for every partition that is visible in My Computer. Please note, that checking the C: drive may require you to reboot the machine.

I think it is because 4.34gb is the correct size of a file for a dvd disc. Remember media makers always overstate the actual capacity of the device, whether it be optical or hard drives. If you want the least amount of wasted space on a dvd, specify a 1492 split size. Three of these will fit on a dvd with very little space wasted.

DwnNdrty has it right. The vendors like using the biggest number which results when K=1000 for converting to GB.

Computers, being binary, actually use K=1024 which is a pure binary number.

To convert the "binary size" 4.38GB = 4.34 *1.024*1.024*1.024 =4.70 GB.

One of the 1.024 is to convert to K, the second for M and the third for G.

In real-life, you also have to allow some overhead for the file system which is likely why 'Acronis reports the size as 4.34 instead of 4.38GB.
