Wikispooks talk:Site Backup

Site database dump shrinkage

For information: On the old server both Piwik analytic and site data were held in the same database. On the new server I've split them such that the dump only contains regular site data. The zipped file is now only 76Mb --Peter P (talk) 17:43, 17 January 2014 (GMT)

Request to improve backups

How about GZipping the daily .sql dump? This should reduce it by about 2/3 - making for a much easier download. Robin (talk) 02:00, 5 January 2014 (GMT)

Agreed. I too have been mulling backups. I think it would also be better to provide just the SQL dump and the /images directory structure. That would obviate the need to provide the entire suite of MW and its extensions and remove any risk associated with LocalSettings.php. We would need to adjust the instructions a bit so that info about which extensions were mandatory + current version info etc, but it would further reduce both backup size and content complexity. I'll have a look. We'll no doubt need to tweek your script. --Peter P (talk) 09:38, 5 January 2014 (GMT)

I've tweeked your script and tested it - backup.3-2.sh - Seems to be OK. It does 2 backups (images directory and ws.sql to Files-date.zip and sqldump-date.zip) and copies both to -latest and deletes old zips as before. The results of the test are in the backups directory now. Another reason to change to just the sql dump and the images directory is the complex set of exclusions which may need to change. We can easily add the MW script and extension files to a separate backup if necessary. I'll start on revising the instructions if you're happy with this. --Peter P (talk) 15:24, 5 January 2014 (GMT)

Progress

I've been pre-occupied with grandchildren today - will be tomorrow too. The revised shell script tested OK. We now have 3 separate sets of aging backups: the files, the images and the software - needed to incorporate the iframeDocs and ClimateChange directories into the files one so that's why it has grown. I should get the instructions finished tomorrow. I've also set up a cron job to push the files and database backups to another server. If you have one with shell access, just give me access credentials and I'll get them pushed there too if you like. --Peter P (talk) 16:05, 6 January 2014 (GMT)

Good work on this. How about keeping a monthly "all in this file" backup as before - for people who don't want to read but just get everything in one click? Robin (talk) 17:00, 7 January 2014 (GMT)

Difficulties?

It seems like you've decided against the 'unzip and go' approach, suggesting people install extensions manually. This increases the difficulty, as well as looking more daunting. Why the change? Robin (talk) 13:59, 14 January 2014 (GMT)

Lots of issues encountered trying to do it the 'easy' way:

Most relate to server dependencies that one might assume (I did) would be met simply by virtue of having the latest LINUX LAMP stack distribution. Not so, and getting to the bottom of missing dependency errors is far from straightforward. The Mediawiki install process checks the environment and enumerates any problems clearly. For example, in this brand new Centos 6.5 test case, php was not compiled with xml or pdo or mysql or mbstring or gd all of which are essential. Neither did the distro include MEMCACHED or APC such that existing statements in the backed up LocalSetings.php produced non-obvious errors. There were a number of other issues too which I can't remember off-hand. Anyway, the upshot was that, rather than try to document all the pitfalls and have a would be backup-user check them all off, it would in fact be far easier to install Mediawiki + extensions conventionally and let it report problems clearly whilst in progress. Doing it that way, I actually yum-installed the needed stuff as the MW install progressed and it was done very quickly.

In any event I doubt the manual extension install process would put off a prospective user because he/she will certainly need more than a modicum of expertise to attempt it --Peter P (talk) 15:30, 14 January 2014 (GMT)

wikispooks.sql??

What is wikispooks.sql? Is it needed? Robin (talk) 07:14, 23 July 2014 (IST)

It is the MySQL database dump - ie the same as ws-latest.zip, but unzipped and done every day. I could put it in a different directory so it would not appear on the list but why bother? --Peter P (talk) 10:13, 23 July 2014 (IST)

Oops, sorry. It is an old backup done whilst upgrading-testing those SMW issues. No longer needed. I'll delete it. --Peter P (talk) 10:25, 23 July 2014 (IST)

BitTorrent and WebTorretn

One way to proliferate these backup zips and easy your bandwidth is to share them via BitTorrent and WebTorrent. Further, I would include a simple text or basic html file with these wonderful DIY instructions. An email announcement every week would be great too so I could just click and co-seed your torrents. ~ JasonCarswell (talk) 19:16, 6 February 2019 (UTC)
