Need backup script.

Hi there,

I am fairly new in linux and got a couple questions regarding scripting. I don't know much about it at all.

What I need it to do is run a cron job on the machine every night around 8:00 PM.

This is what I'd like it to do:

- take two files from a commonly accessible area: x.file + y.file

- archive and compress the two: x.file + y.file ==> x+y.tar.gz

- name the new file with a date in it: x+y_130706.tar.gz

- ftp the file to a remote location: ftp://remote.location.com/x+y_130706.tar.gz

I just don't know how to write the script for that. I can't imagine it being too difficult. And I wouldn't mind learning to script some things myself.

I am running Fedora Core 5 on the system, and was wondering what cron program I could use as well.

Thanks.

If root backs up files:

Code:

echo "* 20 * * * root /root/bin/backup.sh" >> /etc/crontab

else modify for your personal "crontab -e"

No checks, no testing, no optimisation, no cleaning up and no ftp (but scp):

Code:

#!/bin/sh
files=( /tmp/x.file "/home/gtrawoger/some dir/y.file" )
arch_d=/tmp; arch_t=$(date '+%Y%m%d')
for n in $(seq 0 ${#files[@]}); do fn="${fn} $(basename "${files[$n]}" .file)"; done
arch_n=$(eval echo fn=${fn:1}|tr " " "+"); t="$arch_d/${arch_n}_${arch_t}.tar.gz"
tar -czf "$t" ${files[@]} && scp "$t" user@host:/some/dir && rm -f "$t"
exit 0

* using DDMMYYYY IMHO ain't good for sorting purposes: use YYYYMMDD.

And I wouldn't mind learning to script some things myself.
Search LQ for "ABS" or "Advanced Bash Scripting" guide.
