Backup with Date and Time

Following is a guide on how to save backups with the date and time. When it gets to 5, or the number you select, each time a new backup is created, the oldest one 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.

# This saves a copy of mydata.tgz with the date and time.

#!/bin/sh
PART=sda1  # If not sda1, change this to the correct partition.
DATE=$(date +"%Y.%m.%d-%H.%M.%S")
DATABACK=Data-$DATE.tgz
cd /mnt/$PART/tce/
cp mydata.tgz $DATABACK

# This deletes the oldest if there are more than 5 (or the number you select).

NUMBACK=$(ls Data-* | wc -l)
while [ $NUMBACK -gt 5 ]  # Change 5 to the number of backups you want to keep.
do
ls -1t /mnt/$PART/tce/Data-*tgz | tail -1 | xargs /bin/rm -f
NUMBACK=$(ls Data-* | wc -l)
done

If you are not using sda1, change it to the correct partition.

Save this 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.

/opt/backdate.sh

You need to be using backup.

Add the following line to /opt/bootlocal.sh

sudo cp /opt/backdate.sh /usr/sbin

Restart the computer.

To run backup, use

filetool.sh -b

To create a backup file with the date and time, use

backdate.sh

Backup files are normally saved in the tce directory, which may be somewhere like /mnt/sda1/tce.

To access the contents of a backup, create a new directory and copy the backup file to it. Open the terminal and type

cd directory
tar -xvf backup-name

To restore a previous backup, remove mydata.tgz, and rename the backup you want to restore mydata.tgz.

Restart the computer for it to be loaded.
