Backup script questions

[MadsRC]

I have created this script from ubuntu wiki pages:

#!/bin/bash
# Backup Script
#
#What to backup.
backup_files="/home/mrc/"
#Where to place backup.
dest="/home/mrc/backup/"
#Create archive filename.
day=$(date +%d%m%Y-%R)
hostname=$(hostname -s)
archive_file="$hostname-$day.tgz"
#Print start status message.
echo "Backing up $backup_files to $dest/$archive_file"
date
echo
#Backup the files using tar.
tar czf $dest/$archive_file $backup_files --exclude 'backup/*' --exclude 'backup'
#Print end status message.
echo
echo "Backup finished"
date
#Long listing of files in $dest to check file sizes.
ls -lh $dest

My question is however, how to I get rid of this line when I run the script:

tar: Removing leading `/' from member names

The script is successfull. BUT I'm getting tired of that line...

I know this doesn't really answer your question, but I'd give up on the method you're trying to develop and jump to rsync. You can exclude directories with this method. rsync has been used and developed for years and is made with one purpose in mind -- backups.

skip long digression about the use of '-P' and the removing of the leading slash .. yadda-yadda.

Ugly little script, '-C' should fix it ... here's the 'braceified' version

#!/bin/bash

BACKUP_FILES="${HOME}/prj/"
DEST="${HOME}/backup/"
DAY=$(date +%A)
HOSTNAME=$(hostname -s)
ARCHIVE_FILE="${HOSTNAME}-${DAY}.tar.gz"

echo "Backing up $BACKUP_FILES to ${DEST}/${ARCHIVE_FILE}"
tar czf ${DEST}/${ARCHIVE_FILE} -C ${BACKUP_FILES}
echo "Backup finished"

HTH ... khay

Thank you Khay.

I'm learning Bash, I know it could be prettier

However, executing that script yields:

Backing up to /home/mrc/backup//mrc-Thursday.tar.gz
tar: option requires an argument -- C
Try `tar --help' or `tar --usage' for more information.
Backup finished

Thank you Khay.

I'd say "your welcome" had I got it right first time ... so, now having tested it

#!/bin/bash

BUP_FILES_DIR="prj"
DEST="${HOME}/backup"
ARCHIVE_FILE="$(hostname -s)-$(date +%F).tar.gz"

echo "Backing up ${HOME}/${BUP_FILES_DIR} to ${DEST}/${ARCHIVE_FILE}"
tar -C ${HOME} -czf ${DEST}/${ARCHIVE_FILE} ${BUP_FILES_DIR}

if [[ $? == 0 ]]; then
    echo ""
    echo "Backup finished"
else
    echo ""
    echo "There was a problem completing the backup"
fi

Note I've changed "date +%A" to "date +%F" ... which seems a little more informative ... you can obviously change it back if you so wish.

best ... khay

Thank you

Found a problem with it though. tar gives an I/O error when untar'ing the backup file created. Both on my server and if I download it to my local pc... Untar'ing it with the gui works though...

Solved it by chaning the time format from ":" to "_"

Used your code to modify my existing, will post it when it's done

Your welcome ...

The date format 'date +%F' is "-" (dash) seperated, there should be no problem with dashes.

OK ... best ... khay

Ah sorry, It was actually my own code that messed it all up.

Think I got it now Wouldn't learn anything if I didn't break stuff
