 # IML BACKUP #
 
-Backup scripts using restic or duplicity.
-Runs on Linux.
+Backup scripts using restic (or duplicity).
+
+Runs on Linux: CentOS, Debian, Manjaro, Ubuntu.
 
 * Free software. GNU GPL 3.0
 * Source: <https://git-repo.iml.unibe.ch/iml-open-source/iml-backup/>
 * Restic: <https://restic.net/>
-* Duplicity: <http://duplicity.nongnu.org/>
-
-## Why ##
-
-We don't want to configure a backup set on a "central backup server" for each new node. Each new node pushed its own backup data to a backup target.
-
-We want to push data from a private network to target; a central backup server would ot reach some clients.
-
-A set of database backup scripts detects exsiting locally running database servers and puts a compressed dump file per database scheme to a local backup directory.
-
-Then a transfer script uses a tool to encrypt and transfer local backups and other local folders to a backup target.
-
-## Features ##
-
-### Database dumps ###
-
-Supported Databases for backup and restore
-
-* Mysql/ Mariadb (mysql_dump)
-* postgres (pg_dump)
-* sqlite (by naming files with full path in a config)
-
-Limited support:
-
-* couchdb (using a config with naming convention)
-* ldap (without restore so far)
-
-### backup tools ###
-
-DUPLICITY
-
-* Incremental and full backups
-* encrypted backups using GPG
-* set size of backup volumes
-* delete old backups by a given time limit
-* several backup targets (we currently use scp:// rsync:// and file://)
-
-RESTIC
-
-* creates an initial full backup - and then never again.
-* encrypts data
-* deduplicates files
-* delete backups by rules to keep a count of hourly, daily, weekly, mothly, yearly backups
-* several backup targets (we currently use sftp:// https:// and file://)
-
-### control simoultanous backups ###
-
-As an optional feature you can control the count simultanous written backups.
-This requires additional effort next to the client installation.
-
-## Installation ##
-
-- Uncompress / clone the client to a local directory
-- go to jobs directory to copy the *.job.dist files to *.job
-- configure *.job files
-- manual test run
-- create a cronjob
-
-### Uncompress client ###
-
-To put all files into a directory i.e.
-
-    /opt/imlbackup/client
-
-then use the **root** user and follow these steps:
-
-    # Create the directory level above
-    mdir -p /opt/imlbackup/
-
-    # download
-    cd /opt/imlbackup/
-    wget https://git-repo.iml.unibe.ch/iml-open-source/iml-backup/-/archive/master/iml-backup-master.tar.gz
-
-    # extract
-    tar -xzf iml-backup-master.tar.gz
-    mv iml-backup-master client
-
-    # remove downloaded file
-    rm -f iml-backup-master.tar.gz
-
-    # to set pwd to /opt/imlbackup/client:
-    cd client
-
-### database backup: set local backup target ###
-
-Create a **jobs/dirs.job** (copy the delivered *.dist file)
-
-    cd jobs
-    cp backup.job.dist backup.job
-
-There are 2 defaults:
-
-    dir-localdumps = /var/iml-backup
-    keep-days = 7
-
-**dir-localdumps**
-
-{string}
-
-The target directory for local dumps. It is used by 
-
-* the database dump scripts
-* the transfer script to store the client backups
-* the restore script
-
-Below that one a directory for the service will be generated; inside that one the database dumbs with scheme name and timestamp, i.e.
-
-    /var/iml-backup/mysql/mydatabase__20190827-2300.sql.gz
-
-**keep-days**
-
-{integer}
-
-The number of days how long to keep dumps locally.
-
-Remark:
-To make a database restore its dump must be located at this directory. To restore an older database you need to restore the dump from duplicity first.
-
-If you have local Mysql daemon or Pgsql you can test it by starting 
-
-    # dump all databases
-    sudo ./localdump.sh
-
-    # show written files
-    find /var/iml-backup
-
-### Define local directories to backup ###
-
-Edit **jobs/dirs.job** again.
-
-There are a few include definitions:
-
-    # ----------------------------------------------------------------------
-    # directory list to transfer
-    # without ending "/"
-    # missing directories on a system will be ignored
-    # ----------------------------------------------------------------------
-    include = /etc
-    include = /var/log
-    include = /home
-
-... and excludes
-
-    # ----------------------------------------------------------------------
-    # excludes
-    # see duplicity ... added as -exclude-regex parameter
-    # ----------------------------------------------------------------------
-
-    # exclude = .*\.(swp|tmp)
-
-    # mac file
-    # exclude = \.DS_Store
-
-    # all subdirs containing "cache/", i.e. any/path/zend-cache/[file]
-    # exclude = cache/.*
-
-**include**
-
-{string}
-
-Multiple entries are allowed. Each defines a starting directory that is backed up recursive.
-
-Do not use a trailing slash "/".
-
-Each include line creates ist own backup volume on the backup target: One duplicity backup command will be started per include.
-
-An include for the database dumps is not needed - it will be added automatically.
-
-Missing directories on a system will be ignored and does NOT throw an error. So you can write a "general" single config and deploy all servers.
-
-**exclude**
-
-{string}
-
-Multiple entries are allowed. Each defines a regex that is applied to all include items. This could have an negative impact. I suggest not to define an exclude - only if it is needed because of huge wasted space.
-
-TODO: advanced stuff ... There is a possibility for directory based include and exclude rules.
-
-### Setup the target ###
-
-Edit **jobs/transfer.job**. This file handles the transfer of local directories
-to a backup target. You find comments in the config.
-
-By default the backp tool "restic" is activated (and recommended). You can switch to duplicity
-if you feel familiar with it.
-
-`bin = restic`
-
-Create a repository base directory with the wanted protocol. This step has to be done
-once for all systems you want to backup. The IML Backup will create a subdirectory
-with the hostname for its backups. Set your target in storage:
-
-`storage = sftp://backup@storage.example.com//netshare/backup`
-
-## Production usage ##
-
-Edit **jobs/transfer.job**.
-
-Set a password to encrypt local data with it. Each system should have its own password.
-Use a long password - i.e. 128 characters.
-Save your password list - if you loose it you cannot restore data anymore.
-
-`passphrase = EnterYourSecretHere`
-
-Change the restore path if needed. A restore does not overwrite the current files.
-
-`restore-path = /restore`
-
-Then have a look to the section with variables that have the prefix of bin = ... (restic_... or duplicity_...).
-
-The index files are stored in $HOME. Because /root partition could be to small for
-systems with many files (fileserver) you can put the index somewhere else:
-
-`*_cachedir = ...`
-
-With this loglevel you get a list of new or changed files in the log:
-
-`restic_verbose = 2`
-
-You can set a tag that is set for backups by script.
-
-`restic_tag = imlbackup`
-
-The mount of backup sets is a restic feature. After mounting a backup there
-you can browse via filesystem through backups and timestamps.
-
-`restic_mountpoint = /mnt/restore`
-
-Define how many backups you wanto to keep. After the backup of a directory
-the cleanup strategy will be applied.
-
-```
-# prune 
-restic_keep-hourly = 100
-restic_keep-daily = 90
-restic_keep-weekly = 12
-restic_keep-monthly = 12
-restic_keep-yearly = 10
-```

-### setup backup times ###
+# Why #
 
-### Create a cronjob ###
+We rollout our linux systems automatically. We try not to configure third systems
+for backup, monitoring and other general services.
 
-### Monitoring ###
+* **No central backup server**: We don't want to configure a backup set on a "central backup server" for each new node. Each new node pushes its own backup data to a given backup target.<br><br>
+* We want to **push data from a private network** to target; a central backup server would not reach some clients without sattelite systems.<br><br>
+* No agent needed.<br><br>
+* **Automatic backup of databases**: A set of database backup scripts detects exsiting locally running database services and puts a compressed dump file per database scheme to a local backup directory.<br><br>
+* We want to use a **local encryption** of all data to backup.
