History: TRIM and Syncthing for automated offsite backups

Preview of version: 8

Use case: I have a Tiki on ClearOS. and I want automatic backups of that Tiki to my local computer for safekeeping. These are high level instructions as to how to combine TRIM and Syncthing to do so.

Setup TRIM

Requirements

Installation

svn co https://svn.code.sf.net/p/tikiwiki/code/trim

Configure TRIM to backup your Tiki site

In this example, we will add an instance named ii. notresuite.com. TRIM and TIKI are in the same server. Pay attention where to input 127.0.0.1.

[root@trimclient trim]# make instance
php -d memory_limit=256M scripts/addinstance.php
Default editor used (nano). You can change the EDITOR environment variable.

You can backup as always.

[root@trimclient trim]# make backup
bash scripts/backup.sh php -d memory_limit=256M
php
which: no cpulimit in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin)
dont use cpulimit
Default editor used (nano). You can change the EDITOR environment variable.
Default diff used (diff). You can change the DIFF environment variable.
Note: Backups are only available on SSH instances.

Which instances do you want to backup?

Set up automatic backups

Of all the instances

https://doc.tiki.org/TRIM#To_setup_automated_backups

For just one of the instances

We will use the PIPE from the Linux bash in order to inject the desired number. In this case, it is the number 3.

[root@trimclient trim]# echo 3 | make backup
bash scripts/backup.sh php -d memory_limit=256M
php
which: no cpulimit in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin)
dont use cpulimit
Default editor used (nano). You can change the EDITOR environment variable.
Default diff used (diff). You can change the DIFF environment variable.
Note: Backups are only available on SSH instances.

Which instances do you want to backup?
[2] vv.notresuite.com                                           m@.com
[3] ii.notresuite.com                                           your@email.com

As you see, no human interaction was needed.
You may want to install this in a cronjob, to do it every day at noon, do the following.

echo '0 0 * * * pushd /root/trim/ && echo 3 | make backup &&  popd' > /etc/cron.d/trim-ii.notresuite.com-backup


Install Syncthing

On the server

On your laptop

Setup Syncthing


The TRIM folder to backup is /root/trim/backup/archive

Make sure Syncthing automatically restarts when you reboot so that you have unattended automatic backups.
