Compression change

[Joseph Hales]

Would it be possible to have fog give me an option to change the compression on an existing image. For example if I am in a hurry to create a new image and upload at low compression I may not have the machine available later to re-upload at the higher compression later for space consideration.

The compression is done directly on the Host computer and then transferred up to the server.

That said there maybe a way to decompress and recompress an image but complications may occur.

@Wolfbane8653 I was thinking the exact same thing.

I say test it out and report back…

Upload with compression at 1.

Decompress - recompress with uber high settings server-side.

Post a sample command line and I will give it a try even if its not in the web gui we could post the command in the wiki.

No idea if this is the best way, but it seems to be working. I’ll let y’all know when it finishes compressing.

for f in *.img; do mv "$f" "${f%.img}-bak.img"; done
for f in *bak.img; do pigz -d -c $f | pigz -9 > "${f%-bak.img}.img"; done
