I've immediately thought to a backend problem: I had a similar case in the past, but in that case opening the storage with CyberDuck show the data in the backend and I received a 404 when I tried to open them. In fact it was a problem that the backend then have solved after my report. Now, however, I did several tests with Cyberduck uploading, downloading and deleting files and it seems that everything is working properly. > > I've runned s3ql_verify but it haven't found corrupted or missing > > objects. > This is quite unlikely.

Moving to another is not so easy, we will have worst performance and probably we need to pay for bandwidth (between Softlayer network it's free). If I were able to reproduce the problem outside of S3QL I could open a ticket with Softlayer to ask for an investigation, but as I said trying with Cyberduck (or other software swift compatible) everything is working correctly. Have you any suggestions to make a more in-depth simulation of read / write on the backend? Thanks Fabio -- You received this message because you are subscribed to the Google Groups "s3ql" group.
