Yes, the script runs perfectly. All the variables are defined at the top of the script. (I did mention that I was removing everything but the command itself to make the post shorter).

Everything runs.. the initial mysqldump.. the rsync.. the deletion of backups older than 2 weeks.. the zipping of everything into 2GB chunks.. the copying of the 2GB chunks to external USB.

The only thing I'm concerned with here is why the resulting 2GB zip chunks can't be unzipped without errors, and I think it's specifically something in the zip command in the last line of the last snippet I posted, but I can't figure out what it is.

Here is the relevant part of the script with variables:

Code:

#!/bin/bash

date=`/bin/date +%Y%m%d_%H%M%S`

dir=/mnt/data/Backups
dirlog=/mnt/data/Backups/logs
dircom=/mnt/data/Backups/website.com
dirdb=/mnt/data/Backups/website.db
dirzip=/mnt/data/Backups/website.zip
dirscript=/home/user/Scripts

source $HOME/.keychain/${HOSTNAME}-sh

# Rsync website.com to local machine
/usr/bin/rsync -Pavzhe "ssh -p 22" --log-file=$dirlog/$date\_website.rsync.log --bwlimit=2500 --skip-compress=jpg/zip --delete user@website.com:'/home/user/' "/mnt/data/Backups/website.com"
# Delete files older than X days
/usr/bin/find $dirdb/*sql.gz -mtime +14 -exec /bin/rm {} \;
/usr/bin/find $dirlog/*.log -mtime +30 -exec /bin/rm {} \;
/usr/bin/find $dirzip/*.z* -mtime +30 -exec /bin/rm {} \;
# Zip site to 2G chunks
/usr/bin/zip -r -s 2g -y -2 $dirzip/website_$date.zip $dircom/

Here's what happens:
The website has approx 120,000 files, including tens of thousands of pre-existing zipfiles in folders.
My script goes to the website and rsyncs everything, the entire hosting account, and brings it to my local computer.
(Those zipfiles on the website, once rsynced to my local machine, can be manually unzipped without any problem whatsoever, so the problem is not with the zipfiles on the site, nor with their rsynced copies on my local machine)
The next step in my script takes the entire rsynced website on my local machine and zips it into 2GB chunks.
As soon as those 2GB zip chunks are created, the 2GB zip chunks cannot be unzipped again without errors. And not 100% errors. A large part of the site unzips properly. But it seems that the pre-existing zipfiles that were on the website are the files which cannot be extracted from the 2GB zip chunks. That's what I'm trying to figure out...
