Following is a guide on how to save a backup or encrypted backup with the date and time. You need to be using backup or encrypted backup. After a predetermined number of backups are created (the default is 5), each time a new backup is created, the oldest is deleted.
The date and time is in the order year, month, day, then hours, minutes and seconds. This keeps the backup files in order.
Open a text editor, and paste the following.
#!/bin/sh # This saves a copy of backup or encrypted backup with the date and time. PART=$(cat /opt/.backup_device) MYDAT=$(cat /etc/sysconfig/mydata) DATE=$(date +"%Y.%m.%d-%H.%M.%S") DATABACK=$MYDAT-$DATE.tgz CRYPTBACK=$MYDAT-$DATE.tgz.bfe cd /mnt/$PART cp $MYDAT.tgz $DATABACK cp $MYDAT.tgz.bfe $CRYPTBACK # This deletes the oldest if there are more than the number you select (the default is 5). NUMBACK=$(ls "$MYDAT"-2* | wc -l) while [ $NUMBACK -gt 5 ] # Change 5 to the number of backups you want to keep. do ls -1t $MYDAT-2*tg* | tail -1 | xargs /bin/rm -f NUMBACK=$(ls "$MYDAT"-2* | wc -l) done
Save this file as backdate.sh in /opt.
Open the terminal and type
sudo chmod 775 /opt/backdate.sh
To create a backup file with the date every time you turn the computer off, add the following to /opt/shutdown.sh.
Add the following line to /opt/bootlocal.sh
sudo cp /opt/backdate.sh /usr/sbin
Restart the computer.
To run backup, use
To create a backup file with the date and time, use
To restore a previous backup, remove mydata.tgz, and rename the backup you want to restore to mydata.tgz.
If using encrypted backup, remove mydata.tgz.bfe, and rename the backup you want to restore to mydata.tgz.bfe.
Restart the computer for it to be loaded.
