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 suite of script intended to help backup and restore when migrating to another box with same SME version or more recent.

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 already known by the script locations for every installed contribs.

It will also backup some user space known to have potential 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. A 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 server backup and restore faster, It assumes you backup those files separately and restore them manually latter (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

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.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.

Default exclusions

Warning.png 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
