Description

I try to run oak-run to back up my repository according to the online documentation, like this:

java -mx4g -jar oak-run-1.10-SNAPSHOT.jar backup repository/segmentstore ./repo.bak

When I do this I get an IllegalStateException:

java.lang.IllegalStateException: Attempt to read external blob with blobId 
[ 3e15c88da9b46267141b60826c0734007c3e5a5f804c953edb0280eda680a9be#174188 ]
without specifying BlobStore

 

It is unclear how to proceed, based on the documentation.  It doesn't tell me how to specify a blob store path.  Expected behavior should be:

1. Tool help gives correct options for correct usage
2. Online documentation gives correct options for correct usage
3. Tool handles exception gracefully instead of throwing stack trace

 

Configuration:  Default Oak setup with SegmentNodeStore and FileDataStore, no custom configuration.  I tested with oak-run built from sources as well as multiple downloaded versions, all gave the same behavior.  Path to repository is correct and I verified the blob actually does exist in the blob store.
