This question did not help me (despite having the same title). So I post this even though this is a duplicate question.
As far as I can tell, the total in
du -k includes all the subdirectories and indicates I have 77 megabytes of data
/raid/fpuData/oldOutput>du -ks 77063332 . /raid/fpuData/oldOutput>tar -cvzf ../oldOutput.tar.zip *
The backup is sill running, but already the file is considerably bigger than 77 megabytes
/raid/fpuData>ls oldOutput.tar.zip -rw-r--r-- 1 nobody nobody 14470610944 Jul 1 22:18 oldOutput.tar.zip
The files I'm backing up are all huge text files filled with numbers, like a huge comma delimited spreadsheet). Something like this
0.3454915028125262743685653,0.5590169943749474512628694,... 0.221761776923297210251107,0.3588180924674668759166707,... -0.06101864995889930837202897,-0.09873024958113109372792593,... -0.3001958820500086333460388,-0.4857271404396689140625654,... ...
Why is the
tar file bigger than the directory? It should be compressed because I'm using the data with the
z option. What's the point of
tarring it, then?
