Recently my computer crashed therfore the claculating was aborted. When I started my computer again, it was not resuming the same work but asked a new one from CP. Are the data of this project (in the meantime 2GB) lost or can I make my computer resuming the started project?

Thanx for assistance

I\'m pretty sure the only way you would be able to resume working on that work unit is if you had a complete backup of the BOINC folder from before the crash. Otherwise, I don\'t think you can recover it.

What constitutes a full backup? I have what appears to be an intact folder for the stopped project analysis. Beyond that, CPDN appears to download four or five complete downloads per project. As long as they don\'t overwrite what was there before, one would think that the intact data of a discontinued project would be interesting, at the very least, for debugging purposes. More to the point, though, we have a discontinued analysis here. Shouldn\'t CPDN be interested, at the very least, that a particular analysis will never be received?

A complete backup isn\'t quite the only way to recover but what you do need is some information from an xml file (client_state.xml or client_state_prev.xml I think) about the old run. If BOINC has started and stopped too many times since the crash this information is lost and the directory from the crashed run is not enough to get it started again.

I don\'t know the full details of doing this, but if you can save a copy of the xml with the information then do post again and hopefully someone who does know the details may be able to help.

If it cannot be restarted the lack of trickles will eventually cause it to be automatically noted that no result will be forthcoming.

Sorry if this isn\'t an answer you wanted to hear.

Visit BOINC WIKI for help

And join BOINC Synergy for all the news in one place.

The critical things that are lost when a crashed model uploads are the result zip file downloaded from the scheduler, the <active_task> section for the result in client_state.xml and the contents of the result\'s links in the slots directory.

If the result has been reported you will also lose the <file_info>, <workunit> and <result> sections for the result from client_state.xml

All of these can be recovered from backups, but additional editing will be required if BOINC has started another result using the slot number the CPDN result had been using.

Some (end of phase?) failures can also cause the result\'s directory structure to be flattened out, leaving a set of post-processed and compressed files (these files are stored in the dataout sub-directory while the result is in progress). If this happens the only way to recover the result is by emptying its directory and restoring it from a backup.
