I am trying to image a drive with SafeCopy and compress the output file on the fly so that it won't take up way too much space. (aka 500GB > 50GB)
Will this command work?
sudo safecopy --stage1 /dev/source | pigz -9 /media/mount/dest.img.gz
Or am I missing something?
- safecopy = image software
- pigz = multi-threaded gzip

I tried to safecopy a user's home, which takes 400 GB on the drive, but the image is 900GB and now it failed due to no space left on a device. What is going on, why is the image so large? – Qwerty – 2014-12-27T01:52:58.963
safecopy copies all data sectors including empty space, thats the reason why its so big, and why i asked this other question about compression ;) – nwgat – 2014-12-27T14:41:06.583
Right, I described my problem wrong. I would deal with same problem as you provided I was able to create the image. What I don't understand and I couldn't even find any info about it is why the image took over 900 GB and failed due to not enough space left on a new 1TB drive, while the whole faulty disk had only 500GB and the partition I was trying to recover had only 400GB. – Qwerty – 2014-12-27T17:36:11.153
