pukcab

the simplest possible incremental linux backup and restore

usage

usage: ./backup.sh [-c config] [-v] [-n]
  -c    path to non-default config file
  -v    verbose tarballing
  -n    do not unmount after backing up

usage: ./restore.sh [-c configfile] [-v] [-s source] [-d destination] [-l level]
  -c    path to non-default config file
  -v    verbose tarball extraction
  -s    source of backup, default is to read target from config
  -d    destination of restore, default is ./restore
  -l    number of incremental backup, default is latest

configuration example

# ~/.config/pukcab.conf
mount /mnt/san
target /mnt/san/backup
source /home/user1
source /etc
exclude /home/user1/.cache
exclude /home/user1/Downloads

configuration items

mount

Single value. Optional.

Path to be mounted before backing up. Will be unmounted unless -n is specified.

target

Single value. Required.

This is the place where the tarballs will be located. Organized by year-month.

example:

/mnt/san/backup/2018-07/backup_0.tgz   # full backup tarball
/mnt/san/backup/2018-07/backup_0.snar  # full backup backup index
/mnt/san/backup/2018-07/backup_1.tgz   # incremental tarball
/mnt/san/backup/2018-07/backup_1.snar  # incremental backup index

This is organized so that each month there is a full backup, and every subsequent backup that month will be incremental

source

Multiple values.

Stuff to copy into the tarball. Files or directories.

exclude

Multiple values.

Stuff to skip when backing up. Files or directories.

This is a straight passthrough to tar, so file globbing is supported.
