LeLutin e28da8c390 borg: add configuration to displace the cache directory
borg will by default create its cache directory in ~/.cache/borg. This
means that during backup runs, borg will read and write quite
extensively from/to this directory.

In some situations, it is rather undesirable to have this amount of IO
activity in this location and it would make sense to tell borg to place
its cache elsewhere. This can help for example with placing the cache on
a hard drive where the added IO load will not have as big of an impact
on other running activity for the system.

This change also makes sure that the cache directory environment
variable is cleared out when the configuration option is unset. This
should avoid unpleasant surprises when this environment variable is set
to some unknown value in the context where backupninja is called, which
could lead to borg reading and writing to random places on the system.

##
## This is an example borgbackup configuration file.
##
## Here you can find all the possible borgbackup options, details of
## what the options provide and possible settings. The defaults are set
## as the commented out option, uncomment and change when
## necessary. Options which are uncommented in this example do not have
## defaults, and the settings provided are recommended.
##
## The defaults are useful in most cases, just make sure to configure the
## destination host and user.
##
## default is 0, but set to 19 if you want to lower the priority.
## an example setting would be:
## nicelevel = 19
##
## Default
# nicelevel = 0
## default is yes. set to no to skip the test if the remote host is alive
##
## Default:
# testconnect = yes
## default is not to limit bandwidth.
## set to a number in kiBytes/second to limit bandwidth usage.
##
## Default:
# bwlimit = 0

## source section
## (where the files to be backed up are coming from)
[source]
## default is to initialize the backup repository if absent
## set to no to skip this step
##
## Default:
# init = yes
## A few notes about includes and excludes:
## 1. include paths do not support any kind of pattern matching
## 2. exclude paths support several types of pattern matching, the default being
## shell-style matching, where, for example, '*' matches any number of
## characters. for more info, see : borg help patterns
## 3. Symlinks are preserved (not followed).
##
## for more info see : borg help patterns
##
## files to include in the backup
include = /opt
include = /srv
include = /etc
include = /root
include = /home
include = /usr/local
include = /var
## files to exclude from the backup
exclude = /var/lock
exclude = /var/run
exclude = /var/cache
exclude = /var/tmp
exclude = /var/lib/mongodb/journal
exclude = /var/lib/clamav
exclude = /var/lib/mlocate
exclude = /var/lib/postgresql

## define extra command-line options for the "borg create" operation.

## Example:
## create_options = --exclude-caches

## Default:
# create_options =
## whether to prune (remove) older backups
##
## Default:
# prune = yes
## keep all backups within this time frame.
## must be defined as a number followed by one of the
## following characters: "H", "d", "w", "m", "y"
##
## this option will be ignored if set to 0
##
## the default is to keep all backups made within the
## last 30 days
##
## Default:
# keep = 30d
## define extra command-line options for the "borg prune" operation.

## Example:
## prune_options = --keep-daily=7 --keep-weekly=4 --keep-monthly=6

## destination section
## (where the files are copied to)

## put the backups under this directory, this must be set!
## an example setting would be:
## directory = /backups
##
## Default:
# directory =
## the machine which will receive the backups.
## an example setting would be:
## host = backuphost
##
## set host = localhost for local backups (no ssh)
##
## Default
# host =
## make the files owned by this user. you must be able to
## `su -c "ssh backupuser@backhost"` without specifying a password.
## an example setting would be:
## user = backupuser
##
## Default:
# user =
## archive name, should be unique every day.
## Format tags available :
## {now}, {utcnow}, {fqdn}, {hostname}, {user}, {pid}
##
## for more info see : borg help create
##
## Default:
# archive = {now:%Y-%m-%dT%H:%M:%S}
## compression algorithm
## can be "none", "lz4", "zstd[,L]", "zlib[,L]", "lzma[,L]", "auto,C[,L]".
## - "none" stands for "no compression"
## - "lz4" offers very high speed, very low compression
## - "zstd" is a modern wide-range algorithm
## - "zlib" offers medium speed, medium compression
## - "lzma" offers low speed, high compression
## - "auto,C" will use a heuristic to decide whether to compress using
## selected algorithm C
##
## for more info see : borg help compression
##
## Default:
# compression = lz4
## encryption mode to use for repository creation
##
## common options are "none", "repokey" or "keyfile"
## - "none" = no encryption
## - "repokey" = encryption with key stored inside the repository
## - "keyfile" = encryption with key stored in ~/.config/borg/keys/
##
## for other options and more info, see : borg help init
##
## Default:
# encryption = none
## passphrase of the key used for repository encryptions
##
## must be set if encryption is not "none"
## encryption is disabled by default
##
## Default:
# passphrase =
## Path to the directory that will hold borg's cache files. By default this is
## empty, which will let borg use its default path of "~/.cache/borg".

## Default:
# cache_directory =
