QUBU creates snapshots of your $HOME. It is written in Python and uses rsync as backend and crond to schedule the backup task.
It’s primary goal is to be a minimalistic, simple and functional backup tool and not to be very eye-candy.
Usage: snapshots.py [options] profile
Options:
-h, --help show this help message and exit
-r PATH, --restore=PATH
restore PATH from snapshot (Full path including
snapshot path)
-c, --clean Remove/reduce old Snapshots
-q, --quiet Decrease Verbose Level (only Warnings and above)
-d, --debug Debug Output
A qubu profile is a normal rsync filter file with two or three header lines starting with a "#". This way rsync will ignore them.
The first line must be the path to the source directory. Normally the value of $HOME. The second line defines the directory path where the backup snapshots should be stored. The third line is optional and defines the rsync command call with its parameters. The default for it is "rsync -aEAXH". Normally you shouldn’t have to change it.
For more details of the rsync filter option take a look into the rsync manpage and documentation.
Your cron daemon should run qubu as a cron job. A cronjob can be create with:
crontab -e
But please take a look at your cron daemon documentation at least take a look at man crontab.
A dcron ( the default cron daemon on archlinux) crontab entry for qubu can look like this:
@hourly qubu.py ~/.qubu/home >> ~/.qubu/home.log 2>&1
This cron job will start qubu every our. The profile is stored at ~/.qubu/home and all output is redirected to ~/.qubu/home
Note: If you don’t redirect the qubu output your cron daemon will try to deliver it via mail.
The crontab entry above works but it will consume nearly all IQ bandwidth and CPU resources it can get. To reduce the consuming you can use nice and ionice:
@hourly ID=qubu nice -n 19 ionice -c2 -n7 /home/trunneml/bin/qubu.py ~/.qubu/home >> ~/.qubu/home.log 2>&1
