partclone quiet option #42

Closed techathan closed 10 years ago

hi

i experiencing the following issue

i use partclone as backup solution from an lvm snapshot. when i create an image using partclone like the following

partclone.ext3 -c -s /dev/hda1 -o hda1.img the remaining time for creating the .img file is about 3 minutes

as soon as i want to use the quiet option

partclone.ext3 -c -q -s /dev/hda1 -o hda1.img

the remaining time becomes over 2hours

when i try to pass the whole through gzip

partclone.ext4 -c -q -s /dev/SERVEUR/system_snap | gzip -5 > /home/system_rescue/system_snap.img.gz

it seems to be a never ending process.

be aware thet without "-q" option partclone with gzip takes about 5 minutes.

also the quiet option makes the partclone logfile too big for beeing readable and freezes the session.

am i doing some thing wrong ? is there a work around.

Kind regards, athan
