Re: [Exist-open] DB corruption and recovery

[Michael W. <wes...@ja...>]

Hi Sava,

My emergency backup script is:

#!/bin/sh
cd ~/exist
bin/run.sh org.exist.backup.ExportMain -x -d ~/backup/full-$1


I run this before removing any of the files in the DATA directory. There
are corrupt files, usually put into __lost_and_found__ in the generated
backup, so I know what to look for in the daily backups.

Hope this helps.

Take care.
