One advantage of a web-based system like MorphoBank is that time-consuming maintenance tasks such as data backup can be centralized. MorphoBank runs on servers hosted by the San Diego Supercomputing Center at the University of California, San Diego (http://www.sdsc.edu). These servers are backed up nightly and serviced by a professional full-time staff of system administrators.

This is all well and good, but how do you know that your data is safe? Sometimes there's nothing more reassuring than having a copy of your data on your own machine, or even several of your own machines. And maybe a few copies on DVD as well.

This is where the MorphoBank data backup tool comes in. The tool allows you to download a copy of your project data at any time. The copy is a snapshot of the project data at the time the backup was initiated.

The backup includes copies of all the originally uploaded media files, so for some projects the download will be quite large. You should balance your need for an up-to-date backup with the required download time. However, we encourage all projects to perform a backup on a monthly basis, or more frequently if required.

To backup your project, go to the Options tab and then click on the Data Backup tab. Then click on the "Download Project Data" button, which will initiate the creation and download of a ZIP-format archive. For large projects, be patient. The creation of the ZIP archive can take some time.

The Download Package

The ZIP archive contains the following items:

Project media

The originally uploaded files for all project media are included in the backup. To minimize the size of the download, files derived by MorphoBank from uploaded media are not included, only the originals. These missing files can, of course, be regenerated from the originals.

Matrices in NEXUS format

All project matrices are included as NEXUS format files. Note that these are "straight" NEXUS files and do not include any links to media that have been added in MorphoBank.

Project documents

All files uploaded into your project using the docs tab are included.

Uploaded NEXUS files

Copies of all NEXUS files uploaded into project matrices are included..

Project data in SDD format

Most, but not all, project data are included in an XML-format file conforming to the Structure of Descriptive Data (SDD) standard (http://wiki.tdwg.org/twiki/bin/view/SDD/WebHome).

A single SDD file is generated for the project and includes:

  • Project information (title, abstract, citation, etc.)

  • Media views

  • Taxonomic names

  • Specimen information, with references to taxonomic names

  • Media, including extended information and references to specimens

  • Characters and states, including references to media

  • Matrices, including references to media
