Problem:

Multiple backup versions available on your disk.

A complement to ordinary backup/archive.

Solution:

Compress selected dirs and or filetypes into zipfiles and name them with a number last showing the version.

A 1 last means -1 day, a 2 means -2 days and so on. My example script below rotates the names
and make a new 0 version.

The pros with this solution are that you have multiple versions directly available.

So if you have overwritten a document two days ago and by mistake deleted to much text, it's very easy just get it back.

Example:

#!/bin/bash
#
#  Do backups for Tore
#
echo "Tores backups  /etc/cron.custom/tags-backup.sh"
BKUPDIR="/home/tore/backups"
echo "backupdir="$BKUPDIR
# let DAY=$(date -u +%w)
# echo "Day="$DAY

# Test if backup dir is mounted.
if test -d "$BKUPDIR"; then
   echo "OK backupdir is available"
else
   echo "WARN backup dir not available"
fi
# Test if backup dir is mounted.
if test -d "$BKUPDIR"; then
   echo "OK backupdir is available, rotating backup zipfiles now."
