$USER backup script

Michael-Sanders

Hi guys. Here's a simple backup script to help archive the contents of your home directory. Currently, it supports six different archiving methods:

tar/bzip, tar/xz, tar/gzip, tar/t7z, rar, zip

If you have any ideas to make it better, I'm all ears...

Code: 
#!/bin/sh

# This script provides a rolling backup scheme for your home directory & prunes
# archives greater than 7 days old, example output: ~/backup/mike-20130101.zip
#
# |||(__) ^  FreeBSD ~/backup script
#  | (  )(   [c]2013 Topcat Software LLC.
#  |--  >_)  http://topcat.hypermart.net 
#  | _||_    All rights reserved. 

# ----------------------------------------------------------------------------

# path to backup directory & name of archive

DIR=$HOME/backup
OBJ=$DIR/$USER-`date "+%Y%m%d"`

# ----------------------------------------------------------------------------

# create ~/backup directory if it doesn't exist

[ -d $DIR ] || mkdir $DIR

# ----------------------------------------------------------------------------

# prune backups, choose one extension of .tbz .txz .tgz .t7z .rar .zip

find $DIR/ -type f -iname $USER-'[0-9]*'.zip -maxdepth 1 -mtime +7 -delete

# ----------------------------------------------------------------------------

# choose archive type: tar/bzip tar/xz tar/gzip tar/7zip rar zip

#tar --exclude=$DIR -jcvf $OBJ.tbz $HOME
#tar --exclude=$DIR --options xz:9 --xz -cvf $OBJ.txz $HOME
#tar --exclude=$DIR --options gzip:9 -zcvf $OBJ.tgz $HOME
#tar --exclude=$DIR -cvf - $HOME | 7za a -mx=9 -si $OBJ.t7z
#rar a -m5 -s -r -ol -x$DIR/ $OBJ.rar $HOME
zip -9r -x$DIR/\* $OBJ.zip $HOME

# ----------------------------------------------------------------------------

# choose notification method (syslog or mail) if backup fails

#ERR=$?; [ $ERR -eq 0 ] || logger -t backup error: $ERR
ERR=$? ; [ $ERR -eq 0 ] || echo backup error: $ERR | mail -s backup $USER

# eof

I'm not usually awake this time of day, but here are a few (sleepy) thoughts:
  • The backups appear to include the backup directory and any older backups therein, which may or may not be what you want.
  • You might want to add command line arguments that allow the user of the script to choose the backup format (e.g. -z for zip) and/or the way to report errors.
  • tar(1) and archivers/zip can both list the files they are archiving, which you could use to (perhaps optionally) generate a table of contents.
  • I recommend checking whether $HOME exists and is not empty.

Hi Fonz.

Well... actually the script specifically does NOT include the backup directory when archiving (see args --exclude, and -x). But some good ideas elsewise =)

You're right, I see it now. Told you I was sleepy :p
