Re: [Duplicity-talk] Compression Levels

[Ben Edwards]

Thanks.  I have a dual core CPU on the box and when doing full backup it is going to around 50%.  Am I correct in thinking duplicity is only using a single core?  I ask as if it is it would deferentially slow stuff down, if not it may be less of a problem.

Also wondering what the default is and if I do go to max compression, or change type is it likely to make much difference.  I am backing up a mixture of different types of documents but there are quire aw images.

check the gpg man page about supported algos and levels and then add something like

--gpg-options="--compress-algo=bzip2 --bzip2-compress-level=9"

as gpg autodetects the compression while decrypting this parameter shouldn't hurt decompression but have an effect on freshly encrypted files only.
