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

This is a script intended to help backup and restore when migrating to another box with the same SME version or newer.

It will create an archive similar to the console usb backup, hence allowing console restore at startup directly after install.

It will backup all the known configurations and files for every installed contribs.

It will also backup some user space known to potentially have manually added files.

It will create a list of rpm currently installed and break them down to ease the install later.

A WIP will be to download the rpms from the repos to allow quick reinstall. Another script will be used later to allow download from a more recent version.

There is also an exclusion list. By default /home/e-smith/files is in this exclusion list so you can have a faster server backup and restore. It assumes you backup those files separately and restore them manually later (or have them on a separate mount point you can easily remount latter), as the server can boot without them on install.


Installation

yum --enablerepo=smecontribs install smeserver-migratehelper

wget http://viewvc.koozali.org/smecontribs/rpms/smeserver-migratehelper/contribs10/migratehelper.sh -O /usr/bin/migratehelper.sh --no-check-certificate

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 your 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.

Script Options

Usage: [ -t Enable Test mode ] [ -n no-check ] [ -v Version ] [ -h Help ]

test mode - does not stop services and run the backup no-check - don't stop and ask questions


Warning.png 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.

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

or simply 

  rsync -aArv 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....

Uninstall

yum remove smeserver-migratehelper

Issues
