Create back-up script and daily cron job

[shabiel]

Here's a sample. Needs to be improved.

#!/bin/bash

# Switch to home directory
cd

# Delete old backups
rm -rv backup/*

# Make new backup directory
bu_date=$(date +%F)
mkdir -p backup/$bu_date

# Backup default region and r directory to backup directory
$gtm_dist/mupip backup DEFAULT backup/$bu_date
tar --exclude '*.o' -czf backup/$bu_date/r.tgz ./r/

# tar into single file and remove directory
tar czvf backup/${bu_date}.tgz backup/${bu_date}
rm -rv backup/$bu_date

Better script

#!/bin/bash

# Switch to home directory
cd /home/vehu/

# Source variables
. /home/vehu/etc/env

# Delete old backups
echo "Deleting old backups..."
rm -rf backup/*

# Get date for file name
bu_date=$(date +%F)

# Make global backup directory
mkdir -p backup/g

# Backup default region
echo "Creating backup of globals..."
$gtm_dist/mupip backup -BKUPDBJNL=OFF DEFAULT backup/g

# Tar and gzip files
echo "Tarring and gzipping routines and globals..."
tar --exclude '*.o' -cf backup/$bu_date.tar ./r/
tar -rf backup/$bu_date.tar -C ./backup/ ./g
if hash pigz 2>/dev/null; then  # Try pigz to speed up gzip, which is the slowest operation here
    echo "Using pigz to gzip..."
    pigz backup/$bu_date.tar
else
    gzip backup/$bu_date.tar
fi

# Delete dat file directory
echo "Deleting gzipped globals backup..."
rm -r backup/g

# Inform the user of the backup directory and size
echo -n "Backed up to /home/vehu/backup/${bu_date}.tar.gz "
echo "Size: " $(stat --printf="%s" /home/vehu/backup/${bu_date}.tar.gz | numfmt --to=si)

# Print file path for scripts
echo /home/vehu/backup/${bu_date}.tar.gz

that better script looks good here. the command line arg -BKUPDBJNL=OFF to mupip backup I'm not 100% familiar with off the top of my head, but the general pattern looks good

[ChristopherEdwards]

only other thing is maybe don't delete the old backup before the new one is taken or at least allow it to have n number on file

Better version

#!/bin/bash

# Exit on error
set -e

# Switch to home directory
cd /home/vehu/

# Source variables
. /home/vehu/etc/env

# Get date for file name
bu_date=$(date +%F)

# Remove today's backup if it exists
rm -f backup/$bu_date.tar.gz

# Make global backup directory, rm old contents just in case
mkdir -p backup/g
rm -f backup/g/*

# Backup default region and turn off journaling
echo "Creating backup of globals..."
$gtm_dist/mupip backup -BKUPDBJNL=OFF DEFAULT backup/g

# Tar and gzip files
echo "Tarring and gzipping routines and globals..."
tar --exclude '*.o' -cf backup/$bu_date.tar ./r/
tar -rf backup/$bu_date.tar -C ./backup/ ./g
if hash pigz 2>/dev/null; then  # Try pigz to speed up gzip, which is the slowest operation here
    echo "Using pigz to gzip..."
    pigz backup/$bu_date.tar
else
    gzip backup/$bu_date.tar
fi

# Delete dat file directory
echo "Deleting gzipped globals backup..."
rm -r backup/g

# Delete old backups
echo "Deleting old backups..."
mkdir backup/tmp
mv backup/$bu_date.tar.gz backup/tmp
rm -f backup/*.tar.gz
mv backup/tmp/$bu_date.tar.gz  backup/
rmdir backup/tmp

# Inform the user of the backup directory and size
echo -n "Backed up to /home/vehu/backup/${bu_date}.tar.gz "
echo "Size: " $(stat --printf="%s" /home/vehu/backup/${bu_date}.tar.gz | numfmt --to=si)

# Print file path for scripts
readlink -f /home/vehu/backup/${bu_date}.tar.gz
