Debian backup

What to backup

From a Debian system the most important folders to backup are:

/etc
/home
/root
/var/backups
/var/log
/var/mail
/var/spool
Other directories: If you make changes here create a cron or anacron job to copy those files to /var/backup/otherdirecories

How to backup

Manually

cd /tmp (make sure there will be enough space)

For /etc do

tar --bzip2 --create --file hostname.etc.tar /etc
tar --list --file hostname.etc.tar.bz2 | less (show the contents)

For /home do

tar --create --file hostname.home.tar /home
tar --delete --file hostname.home.tar home/user/.cache/ home/user/.thumbnails (per user)
bzip2 hostname.home.tar
mv hostname.home.tar hostname.home.tar.bz2

For /root do

tar --create --file hostname.root.tar /root
tar --delete --file hostname.root.tar root/.cache/ root/.thumbnails
bzip2 hostname.root.tar
mv hostname.root.tar hostname.root.tar.bz2

For /var do

tar --bzip2 --create --file hostname.var.tar.bz2 /var/backups /var/log /var/mail

With a program

T.b.d. See Useful programs or build a script yourself or combine the two

backup-manager

Backup from

 /etc /home /root /var/log/ /var/mail/ /var/spool

to

/var/backup-manager

preferably on a second drive

anacrontab

The /etc/anacrontab entries. Every third day a backup is made. Every day new files are copied to the external harddiskdrive

3 3 Backup-manager /usr/sbin/backup-manager --verbose; echo "backup manager has ran"
18 1 3 Copy-to-External_HDD rsync --recursive --update --delete --progress --verbose /var/backup-manager/ /mnt/External_HDD/backup-manager/

Android

SSH and rsync

See:

Using termux to synchronise with remote machines
SSH and rsync for android termux
Set a cronjob on Termux
Use the Termux JobSchedulerAPI
P.S. For manual, incidental, backups you can also use Midnight Commander in Termux. Install: pkg install mc
