Hi Folks,

We have performed archiving of a directory with -subdir=yes option. it got successfully completed without any failure but the bytes transferred is less than data size on disk [du -sh output]

Is the data exactly 18TB, or is this rounded? What is the exact number reported by 'du -s'?

Is the total number of objects reported by TSM the same as reported by the system?

I agree with Marclant - the numbers match. Just be aware of conversion: TB (tera bytes) is not the same as TiB (tebi bytes). The former has a divisor of 1000 while the latter has a divisor of 1024.

TSM reports in TiB.
