The .tar extension means two or more files are bundled together into a single file. The .tar.gz means compression.
|
|
|
|
Tarballs come with a number of arguments.
|
|
|
|
## More Compression
|
|
|
|
Extremely compressed files take longer to compress, but take up less disk space.
|
|
|
|
> tar cfj super-compressed.tar.bz2 file1 file2

# ssh backup
|
|
|
|
Back up an unmounted partition with ssh:
|
|
|
|
> sudo dd if=/dev/sda1 | ssh -C ghost@192.168.0.10 "dd of=/home/ghost/backup.img" status=progress
|
|
|
|
# `xz`
|
|
|
|
Install `xz`.
|
|
|
|
Unzip the image with:
|
|
|
|
> unxz void.img.xz
|
|
|
|
This then deletes the .xz file. To keep it:
|
|
|
|
> unxz --keep void.img.xz
|
|
|
|
# `zip`
|
|
|
|
Zip file1-3, and make a zip file called 'newsip.zip'.
|
|
|
|
> zip newsip file1 file2 file3
|
|
|
|

|
