Hi,

we are about to start a field survey. How safe is it to update Collect Server/Mobile during the field campaign? Can a mischief lead to data loss? Is it possible to roll back to the previous version?

Thanks for your input!

Hi,

Regarding Collect desktop, each time you update it using the Autoupdater, a copy of the SQLite database (the collect.db file that contains all your data) and a copy of the collect.war file (that basically is all the application) is stored into a subfolder "backup" inside c:\opt\openforis\collect\tomcat. There is not an automatic way to restore a previous version of Collect if something went wrong with an update, but you can use these backup files to recover a previous version of the application.

If you are updating Collect without the Autoupdater and using simply a new .war file, please take a copy of the old database and .war files.

If you are using a PostgreSQL database, you should take a full backup of it using the tool PgAdmin.

In general you should take backup copies of your data frequently and store them in different places outside of you server machine, for example in a external hard drive or in the cloud (Google Drive, Dropbox and so on).

Thanks.

While there shouldn’t be any issues when updating Collect Mobile while in the field, it’s still safest not to. I would suggest that you test the complete survey using the latest Collect Mobile version before going out in the field, to make sure everything works properly. Then disable auto-update for apps in the Google Play store.

Just like for Collect Desktop, you should make frequent backups of the data, to prevent data loss.
