Problems with fixed size splitting
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

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.
