Mit Rdiff-backup lokalen Linux Host nach Windows/Linux sichern

ghostadmin · 16.08.2012

Da ich selbst nur einen Linux Server habe, der ständig läuft - funktionieren die meisten Backuplösungen schlecht, da meistens die Dateien von einem Backupserver geholt werden. Ich will diese vom Server aus wegschicken, auf entfernte Rechner die nicht ständig an sind. Und das ganze soll automatisch und mit eMail versendeten Logs funktionieren, denn wie schnell vergisst man zu sichern. Eine Sicherung auf eine USB Festplatte kommt für mich nicht in Frage.
Ausserdem will ich mehrere Generationen sichern können mit möglichst wenig Platzbedarf. Rdiff-backup arbeitet blockbasiert und wenn man eine Datei ändert, dann werden beim nächsten Backup nur die Änderungen in dieser Datei gesichert. Dies ist mit rsync und dergleichen nicht ohne aufwendige Scripts möglich.

Mit dem Script kann man ein Passwort geschütztes rar Archiv erzeugen z.B. für Configfiles die auf dem Remotesystem nicht für jedermann lesbar sein sollen.
Diese Archive sollten aber nicht zu groß werden, da dann die Deduplikation von rdiff-backup nur eingeschränkt funktioniert.
Man kann wahlweise auf einen entfernten Windows Host (Option backupwin) oder Linux/Unix Host (backupssh) mehrere Pfade per rdiff-backup sehr platzsparend in mehreren Generationen sichern.
Es kann eingestellt werden, ab welchen Datum alte Backupfiles automatisch verfallen (older than).
Dadurch das gleichzeitig ein Linux und Windows Host angesprochen werden kann, kann man auch doppelt sichern.

Wenn die Variable daycheck aktiv ist, läuft das Script nur max. 1x pro Tag. Dies hat denn Zweck falls der Remote Host z.B. ein Windows PC ist der nicht ständig läuft, man das Script z.B. alle 5min. per cron starten kann, solange bis der PC verfügbar ist. Dies wird per Ping und Datum des Logs überprüft und es gibt einen weiteren Zeitwert mit dem gesteuert wird, nach wie vielen Sekunden das Backup startet ab der Ping response.

Nach erfolgtem Backup kann automatisch eine Mail mit dem Log versendet werden.
Ab einer gewissen warning disk space Grenze wird separat eine Warning Mail versendet und beim critical Wert stoppt das Script vollständig.

Zusätzlich gibt es menügesteuerte Optionen um sich auf dem Windows Share ein ext volume anlegen zu lassen (createloop), welches loopmount gesteuert wird. Dieses Loop mounten ist notwendig, weil Windows Probleme mit dem Dateiformat von Linux hat.

Bei einem entfernten Linux/Unix Host kann man die ssh Konfiguration, durch Option createssh erledigen lassen. Hierbei wird es möglich sich ohne Passwort per ssh zu verbinden, weil beim ssh Befehl kein Passwort mitgeliefert werden kann ist dies leider notwendig.

Die Mount Switches dienen dazu um einen Restore machen zu können. Hierzu lässt sich auch rdiff-web nutzen.

# What this script does: 
# You can backup your local data to other Windows, Linux or Unix hosts, by using rdiff-backup.
# Rdiff-backup is working on block level, so multiple generations are really small in size.
# If you want to backup to Linux/Unix, then package rdiff-backup needs to exist on the other host and should be the same version if possible.
# Also ssh needs to be configured, this can be done by using the createssh option.
# If Windows is the backup target, then you need to configure SMB and a loop mount. This can be also done by using the createloop option.

# Additionally you can use the backupconfig section, which backup folders to an archive.
# For example: To backup data such as files including passwords, typically /etc folder.
# Please note that block level backup works very limited on archives. So dont use this for big amount of data.

#CIFS share as target for backup

#This is done because linux cannot handle lower/upper case files.
#You can also use the createloop option to let this do for you.
#Instructions: On your SMB share create a big file enough to fit backup, format it with linux file system and change
#script parameters, before using it. Or start script with createloop option.
#If you have problem with corrupted backups, check output of /var/log/kern.log,
#normaly this is related to linux fs mount options.

#scp ~/.ssh/id_rsa.pub username@host:~/.ssh/authorized_keys
#chmod 600 key files and authorized_keys file on both systems afterwards
#now it should be possible to ssh into other system without password
#step2: to make it possible that user root uses rd_rsa file of that other user
#create /root/.ssh/config file
#enter the following:
#host targethost
#hostname targethost
#user username
#identityfile /home/trechber/.ssh/id_rsa
