An archive that becomes damaged (and the next action to run couldn't auto-repair it), the archive must be repaired before it can be used again.
This is a precautionary measure; QRecall has discovered something is wrong with the archive and, until it is repaired, QRecall cannot guarantee the veracity of its contents. Recalling items from a damaged archive is suspect and further modification of the archive may cause additional data loss. QRecall errs on the side of caution, refusing to use the archive until it is repaired.
The log or status window should definitively indicate when an archive is damaged and needs to be repaired.
The first step is to find the problem (usually in the log) that caused the archive to become damaged.
Also send a diagnostic report if any QRecall process repeatedly crashes or terminates abnormally.
You can automatically repair an archive by creating a repair action that runs whenever QRecall determines that the archive is damaged and can't be auto-repaired.
The special Archive Needs Repair event will cause the action to run the moment QRecall realizes that there's something wrong with the archive that can't be easily fixed.
This is one of the actions the capture assistant will create for you.
