backups

I know that I should have done it sooner rather than pray to the great god of backup for forgiveness after the event! Well I think I might have caught this one in time if you can help?
I need to backup all the files I have on the CGI server, some are php but there are a load of uploaded photographs as well. In addition I need to backup the data held in MySQL. The question is what is the best tool for the job. I would have used the SSH login if it was available but since that is no longer an option, any ideas?

Re: backups

Hi Tony,
I guess backing up the db you'd still do using phpmyadmin export tab at https://mysql.plus.net/
For the rest, no login, but you can run non-interactive shell scripts like
#!/bin/bash
echo "Content-type: text/plain"
echo
tar -cvvzf foo.tar.gz foo/

(tar.cgi upload as ascii and set mode 0700 then request in browser) would pack up your foo folder into foo.tar.gz and
#!/bin/bash
echo "Content-type: text/plain"
echo
tar -xvvzf foo.tar.gz

would unpack it again. Down/upload and delete using ftp. Not most elegant but works.

Re: backups

You could do something like this in a similar vein, but includes the mysql databases and emails the finished file to you.

#!/bin/bash
echo "Content-type: text/plain"
echo
# Add in your mysql details here
MYSQL_USER=
MYSQL_PASSWORD=
MYSQL_DATABASE=
# Add in your email address
EMAIL=
BACKUPFILE=backup.tar.gz
DATE=$(date +'%Y-%m-%d')
BOUNDARY=$DATE/backup+++
cd ~
mysqldump --opt -u$MYSQL_USER -p$MYSQL_PASSWORD $MYSQL_DATABASE > $MYSQL_DATABASE.sql
tar -cvf - . | base64 > $BACKUPFILE.base64
rm $MYSQL_DATABASE.sql
cat <<EOF> $BACKUPFILE.head
From: <$EMAIL>
MIME-Version: 1.0
Content-Type: multipart/mixed; boundary="$BOUNDARY"
This is a multipart message in MIME format.
--$BOUNDARY
Content-Type: text/plain; charset=ISO-8859-1; format=flowed
Content-Transfer-Encoding: 7bit
Please find backup.tar.gz attached
--$BOUNDARY
Content-Type: application/octet-stream; name="$BACKUPFILE"
Content-Transfer-Encoding: base64
Content-Disposition: attachment; filename="$BACKUPFILE"
EOF
cat $BACKUPFILE.head $BACKUPFILE.base64 | mailx -s "Daily backup for $DATE" $EMAIL
rm $BACKUPFILE.head $BACKUPFILE.base64

I've just knocked this up off the top of the head so it might need some tidying and testing, but it should work,

And remembered to base64 the thing on a Friday afternoon.  Cool

Re: backups

Duly deFridayed and tested a bit:
#!/bin/bash
echo "Content-type: text/plain"
echo
# Add in your mysql details here
MYSQL_HOST=
MYSQL_USER=
MYSQL_PASSWORD=
MYSQL_DATABASE=
# Add in your email address
EMAIL=
# Select files to backup
# . backs up everything
# or select files and folders
# between quotes, e.g.:
# "mysql_backup.sql wordpress/wp-content/ foo.txt bar/foo.txt"
BACKUPFILE="mysql_backup.sql"
# Nothing more to add
DATE=$(date +'%Y-%m-%d')
cd ~
mysqldump --opt -h $MYSQL_HOST -u $MYSQL_USER -p$MYSQL_PASSWORD $MYSQL_DATABASE > mysql_backup.sql
cat <<EOF> tmpfile.txt
To: $EMAIL
From: $EMAIL
Subject: Backup on $DATE
MIME-Version: 1.0
Content-Type: multipart/mixed; boundary=$DATE-backup
--$DATE-backup
Content-Type: text/plain; charset=ISO-8859-1; format=flowed

See attached.
--$DATE-backup
Content-Type: application/x-tgz
Content-Disposition: attachment; filename=backup.tar.gz
Content-Transfer-Encoding: base64

tar -cvzf - $BACKUPFILE | base64 >> tmpfile.txt
cat <<EOF>> tmpfile.txt
--$DATE-backup--

cat tmpfile.txt | /usr/sbin/sendmail -t -i
rm tmpfile.txt mysql_backup.sql
echo "Backup sent to "$EMAIL
