Hi Omar,
I am sorry to hear that. BaseX provides some basic recovery mechanisms, but it does not cover all cases that may happen (and of course it is always too late to give the advise to do regular backups when a failure occurs…).
If OPTIMIZE ALL fails, a simple OPTIMIZE works sometimes, but I guess not in this case?
In general it's a good sign if INSPECT reports no errors. I could have a look at the database this week (for free, as I cannot promise anything).
Best, Christian

Hi!
We had some serious problems with our storage last week and unfortunately that killed one of our important BaseX databases.
Is there any way to restore the data?
Does BaseX GmbH provide paid data rescue services?
The symptoms are:
There is data in that database:
