James____ : hi anyone familiar with g4l?, I backup my laptop with the lzop compression but the iamge is 50 gig... even my laptop is just a clean slack13.1 install
adrien : g4l? and lzop isn't meant for hihgh compression
James____ : ghost4linux
James____ : how can i get the image smaller, or make it to iso or something so it become smaller
adrien : James____: use bzip2 or xz/lzma2
adrien : (I prefer xz/lzma2)
Master-Passe : James____: if g4l makes the image just by copying every bit from harddrive then image is size of harddrive
Master-Passe : if you don't use some compression
ananke : James____: as noted in ##linux, your issue is related to the fact that you're backing up the entire block device [or partition], rather than a filesystem
adrien : if it's quite 'dumb', you might also 'dd if=/dev/zero of=~/crap bs=1M', it'll help compression
ananke : compression won't do much good if you're backing up unused disk space [which is full of junk eventually]
adrien : what I said will also make recovery of any deleted file impossible
James____ : I used the default lzop encryption
adrien : well, you might want of=/tmp/crap instead, it depends on the partition
adrien : s/encryption/compression/
James____ : err
James____ : compression
James____ : :)
James____ : so the lzop image i have can i somehow make it smaller
James____ : or must i make a new g4l image with another compression
adrien : the best thing would be to tar instead of ghost
adrien : do you want to backup the files or do you have a specific need for the whole drive/partition rather than only its content
ananke : James____: how can you make a truckfull of garbage smaller? by not packing a truck full of garbage in the first place
James____ : so if making new images
James____ : which compressions must i use in g4l
adrien : ananke++
adrien : well said :-)
ananke : James____: doesn't really matter
James____ : it has gzip,lzop,gzip2
Master-Passe : James____: non of those helps
James____ : it says in documentation lzop will be smaller and run faster
ananke : James____: lzop is fine. again, the issue is not with compression
adrien : lzop faster than bzip2? tell me who wrote that so I can burn him
Master-Passe : :D
adrien : s/faster/smaller/ of course ;-)
James____ : so i should try with bzip2 intead of lzop?
ananke : wow. it's like a brick wall
Master-Passe : :D
