Version

Contrib 10:
smeserver-migratehelper
The latest version of smeserver-migratehelper is available in the SME repository, click on the version number(s) for more information.


Description

Il s'agit d'une suite de scripts destinée à faciliter la sauvegarde et la restauration lors de la migration vers une autre machine avec la même version de Koozali SME ou une plus récente.

Elle créera une archive similaire à la sauvegarde USB de la console, permettant ainsi la restauration de la console au démarrage directement après l'installation.

Elle sauvegardera tous les emplacements déjà connus par les scripts pour chaque contribution installée.

Elle sauvegardera également tout espace utilisateur connu pour contenir des fichiers ajoutés potentiellement manuellement.

Elle créera une liste des paquets actuellement installés et les décomposera pour faciliter l'installation plus tard.

Une étape consistera à télécharger les paquets depuis les dépôs pour permettre une réinstallation rapide. Un script sera utilisé ultérieurement pour permettre le téléchargement à partir d'une version plus récente.

Il existe également une liste d'exclusion. Par défaut, /home/e-smith/files se trouve dans cette liste d'exclusion. Vous pouvez donc avoir une sauvegarde du serveur et une restauration plus rapide. Cela suppose que vous sauvegardiez séparément ces fichiers et que vous les restauriez manuellement plus tard (ou les avoir sur un point de montage séparé, vous pouvez facilement remonter ce dernier), car le serveur peut démarrer sans eux lors de l'installation.

Installation

yum --enablerepo=smecontribs install smeserver-migratehelper

Usage and behaviour

You must first create the mount point and mount your external disk already formatted and with sufficient place to receive the archive:

mkdir /mnt/backup
mount /dev/mydisk /mnt/backup

You can then edit the script and Add you directories or files to include in the dir.list section, your exclusion in exclude.list section. Then check all your contribs are listed, and the associated destination are correct.

vim /usr/bin/migratehelper.sh

Then run the script

  Warning:
When starting this script :

it will create the list of files to backup, then it will stop services that could modify your backup

  • qmail.service
  • qpsmtpd.service
  • sqpsmtpd.service
  • ejabberd.service
  • smb.service
  • smbd.service
  • nmbd.service
  • httpd-e-smith.service

Do a pre-backup event and then create the tar file in /mnt/backup/smeserver.tgz


/usr/bin/migratehelper.sh

It will then process all the files to backup and display the progress on screen. After creating the definitive list depending on installed rpms, it will then Create a list of rpm installed and breakdown them in two easy to restore lists :

files description
/root/newrpms output of /sbin/e-smith/auditiools/newrpms
/root/contribs previous output filtered for smeserver-* rpms
/root/rpmsextra all other non base distro rpms.

Default backup list

note : we are excluding /home/e-smith/{files,shares} and /home/e-smith/db/mysql*/{daily,hourly}

also we add any non rpm owned files in

/usr/local/bin/
/etc/cron.*
/etc/udev/rules.d/

Default exclusions

  Warning:
When starting this script :

/home/e-smith/files /home/e-smith/shares are EXCLUDED by default, because we expect a huge amount of user data that you could rsync later after having your new server up and running, and kept the old one up. This will allow you to be up and running faster than waiting to gzip gigabyte of data, transfer them and ungzip them.

Restore

First step will be to simply use the console restore with the obtained smeserver.tgz. We expect you handle the transfer either using a USB disk, or by having used sshfs and already mounted one extra partition of your new server to your old to create you archive on.

Second use the configuration console to fixe any changes needed on network card or IP, domain name...

Third you can use the saved list of rpm to try to install your contribs and other missing things

 yum install --enablerepo=smecontribs `cat /root/contribs`
 yum install --enablerepo=smecontribs `cat /root/rpmsextra`

You can also enable the needed repo depending on what you would have : epel, fws, ....

Fourth, you can start a rsync for the missing bits

 rsync -arv root@oldsme:/home/e-smith/files/ibays/ /home/e-smith/files/ibays
 rsync -arv root@oldsme:/home/e-smith/files/shares/ /home/e-smith/files/shares
 rsync -arv root@oldsme:/home/e-smith/files/users/ /home/e-smith/files/users
 rsync -arv root@oldsme:/home/e-smith/files/nextcloud home/e-smith/files/nextcloud

or simply

  rsync -arv root@oldsme:/home/e-smith/files/ /home/e-smith/files

Some might enjoy to get back their old log too

then you should be good to enjoy your new server....

yum remove smeserver-migratehelper
