Hi all,
we use the RepositoryCopier to backup our repository. That works good
for us until we had a power breakdown during the backup process. The
RepositoryCopier was copying the repository when the power cuts off. The
next start of Jackrabbit was unsuccessful. We could not start Jackrabbit
anymore until we deleted the lucene indexes from disc. After that it
seems that jackrabbit works correctly.
My question is: Is there a potential risk of data corruption (or data
loss) in jackrabbit when a power breakdown occurs? Is that issue related
to the RepositoryCopier or could we get the same error without it?
You don't say what O/S you are using, but I think the best advice here
is invest in an UPS (Uninterruptible Power Supply)
The most probable cause of your original problem was that filing system
updates had not been flushed to disk. That has nothing to do with
Lucene, Jackrabbit,
Java or even the operating system.
Providing power backup is the only sensible practice when dealing with
sensitive data.

However, I do not have a stack trace anymore and it seems that it
happens not all the time if we try to fake a power breakdown.
Any ideas what causes the problem?
We are using Jackrabbit 1.6.0
