Backup script problems

scotchboy · 07-24-2006, 01:05 PM

I am having a problem with my backup script. I am new to this. I am running Suse Linux and using rsync to backup some of my servers to this server. I want to use cron to run a bigger script than this, but I have a problem with the script. When I run the script, it works the first time, but all the directories that have been moved are named (for example):
backup.20%0d
rather than:
backup.20

I need to know why it puts the %0d after the directory name.

Below is the script, why is this happening? Please help.

-----------------------------------------------
rm -rf /backups/test/vol1/backup.20
mv /backups/test/vol1/backup.19 /backups/test/vol1/backup.20
mv /backups/test/vol1/backup.18 /backups/test/vol1/backup.19
mv /backups/test/vol1/backup.17 /backups/test/vol1/backup.18
mv /backups/test/vol1/backup.16 /backups/test/vol1/backup.17
mv /backups/test/vol1/backup.15 /backups/test/vol1/backup.16
mv /backups/test/vol1/backup.14 /backups/test/vol1/backup.15
mv /backups/test/vol1/backup.13 /backups/test/vol1/backup.14
mv /backups/test/vol1/backup.12 /backups/test/vol1/backup.13
mv /backups/test/vol1/backup.11 /backups/test/vol1/backup.12
mv /backups/test/vol1/backup.10 /backups/test/vol1/backup.11
mv /backups/test/vol1/backup.09 /backups/test/vol1/backup.10

mv /backups/test/vol1/backup.06 /backups/test/vol1/backup.07
mv /backups/test/vol1/backup.05 /backups/test/vol1/backup.06
mv /backups/test/vol1/backup.04 /backups/test/vol1/backup.05
mv /backups/test/vol1/backup.03 /backups/test/vol1/backup.04
mv /backups/test/vol1/backup.02 /backups/test/vol1/backup.03
mv /backups/test/vol1/backup.01 /backups/test/vol1/backup.02
mkdir /backups/test/vol1/backup.01
cp -al /backups/test/vol1R/current/* /backups/test/vol1/backup.01

Hmm, interesting. Not sure why it would append that. But, wow, what a script

. Why not tar and gzip the backups? That way, it doesn't take up as much space. Something like this:

Code:

#!/bin/bash

DATE=`date +%Y%m%d`
DIR="/backups/test/vol1R/current/"
BACKUPDIR="/backups/test/vol1/"

tar czvf - ${DIR} > ${BACKUPDIR}backup${DATE}.tar.gz

By appending the date next to the backup, you have a way of knowing when the backup was performed.

This backup script wasn't uploaded from a windows machine or anything, was it? %0d, taken as hex for an ASCII character, is the \r character used in windows line endings.

you can remove the \r characters of your script by doing

Code:

cat script | sed s/\\r//g > .tmp
cat .tmp > script
rm .tmp

I appreciate the help. What I did to fix it was retype everything on the linux box. I had originally typed the text on a windows pc and when I got it to the linux box, copied and pasted the text into my script file. I still don't know why that wouldn't work, but its done. Thanks Steve

It just got an extra (nonprintable) character tacked onto the end of each line. Glad you got it working now.
