<div dir="ltr"><div>Hi Hussein,</div><div>The situation you have described is very feasible and there are ways it can be mitigated. It is important to have a Disaster Recovery Strategy (see <a href="http://wiki.lib.sun.ac.za/index.php?search=backup&title=Special%3ASearch&go=Go">http://wiki.lib.sun.ac.za/index.php?search=backup&title=Special%3ASearch&go=Go</a>).</div><div><br></div><div>Depending on your server setup, you can backup the whole machine where your repository is running (if you are using a virtual machine) or the important files (Database, Assetstore, configurations, customisations, statistics and any other you may consider important) in case of 'bare metal or physical server' setup. The backups should be stored on a different device from the machine running the repository and if possible a copy of the backups stored offsite. Once you run into problems you can easily recover from the backups.</div><div><br></div><div>Thanks</div><div>Nason</div></div><div class="gmail_extra"><br><div class="gmail_quote">On 31 August 2017 at 10:34, Hussein Suleman <span dir="ltr"><<a href="mailto:hussein@cs.uct.ac.za" target="_blank">hussein@cs.uct.ac.za</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi Colleagues<br>
<br>
I have to agree with Bruce.<br>
<br>
Has anyone ever tried to recover metadata and digital objects from a repository where the operating system is no longer operational? Or where the operating system cannot be run so all you have is a file-based backup of the data? In such cases, most of the recommended systems fail quite miserably.<br>
<br>
We do need to think of long term, maintenance, transfer, recovery, etc. when we evaluate repository tools. Or we should stop using the word preservation.<br>

Hi all,<br>
<br>
I have started editing a collection on ScienceOpen for Data Infrastructures<br>
<a href="https://www.scienceopen.com/collection/data-infrastructures" rel="noreferrer" target="_blank">https://www.scienceopen.com/co<wbr>llection/data-infrastructures</a><br>
<br>
One of the articles I added to this was<br>
"Open Source Software for Digital Preservation Repositories: a Survey"<br>
(<a href="https://arxiv.org/abs/1707.06336" rel="noreferrer" target="_blank">https://arxiv.org/abs/1707.06<wbr>336</a>)<br>
<a href="https://www.scienceopen.com/document?vid=933ee8dc-4123-47e8-8905-661cbaff70e2" rel="noreferrer" target="_blank">https://www.scienceopen.com/do<wbr>cument?vid=933ee8dc-4123-47e8-<wbr>8905-661cbaff70e2</a><br>
<br>
This seems to be the most recent survey on the topic. I have found all<br>
of these "surveys" to be biased and limited in scope, even though many<br>
of them purport to be objective studies. There is not enough weight<br>
given to the long-term operation and maintenance of these things, and<br>
no consideration of how they would exist in a wider data<br>
infrastructure environment. "Libraries" (using a wide meaning of<br>
"place where information and data is curated" need to talk to other<br>
parts of e-Infrastructure. Not many of these digital preservation<br>
repositories do that. Of course, my very opinion is also biased, so<br>
that that as you may.<br>
<br>
I would like to invite anyone who has scholarly material on this kind<br>
of thing to suggest it for the collection, and let me know if you<br>
would like to write an editorial or a review (or just re-publish one<br>
you already have).<br>
<br>
Thanks !<br>
Bruce<br>
