      Hi, sorry for the long break. i'll continue here for my colleague AlexD2006. We have now also tried with the current version (deeb3) of Xen-Orchestra, the problem remains the same. But we have now noticed other error messages (also with the old version) that appear during a delta backup ("base VDI is not a vhd; cannot compute differences"): May 23 16:40:35 xcp-mono02 xapi: [error||7644621 HTTPS 10.32.1.159->:::80|[XO] Exporting content of VDI test-vm.test 1 R:2e892fda7776|vhd_tool_wrapper] base VDI is not a vhd; cannot compute differences May 23 16:40:37 xcp-mono02 xapi: [error||7644621 :::80||backtrace] [XO] Exporting content of VDI test-vm.test 1 R:2e892fda7776 failed with exception (Failure "base VDI is not a vhd; cannot compute differences") May 23 16:40:37 xcp-mono02 xapi: [error||7644621 :::80||backtrace] Raised (Failure "base VDI is not a vhd; cannot compute differences") May 23 16:40:37 xcp-mono02 xapi: [error||7644621 :::80||backtrace] 1/14 xapi Raised at file stdlib.ml, line 29 May 23 16:40:37 xcp-mono02 xapi: [error||7644621 :::80||backtrace] 2/14 xapi Called from file ocaml/xapi/vhd_tool_wrapper.ml, line 206 May 23 16:40:37 xcp-mono02 xapi: [error||7644621 :::80||backtrace] 3/14 xapi Called from file ocaml/xapi/export_raw_vdi.ml, line 50 May 23 16:40:37 xcp-mono02 xapi: [error||7644621 :::80||backtrace] 4/14 xapi Called from file lib/xapi-stdext-pervasives/pervasiveext.ml, line 24 May 23 16:40:37 xcp-mono02 xapi: [error||7644621 :::80||backtrace] 5/14 xapi Called from file lib/xapi-stdext-pervasives/pervasiveext.ml, line 35 May 23 16:40:37 xcp-mono02 xapi: [error||7644621 :::80||backtrace] 6/14 xapi Called from file lib/xapi-stdext-pervasives/pervasiveext.ml, line 24 May 23 16:40:37 xcp-mono02 xapi: [error||7644621 :::80||backtrace] 7/14 xapi Called from file lib/xapi-stdext-pervasives/pervasiveext.ml, line 35 May 23 16:40:37 xcp-mono02 xapi: [error||7644621 :::80||backtrace] 8/14 xapi Called from file ocaml/xapi/export_raw_vdi.ml, line 90 May 23 16:40:37 xcp-mono02 xapi: [error||7644621 :::80||backtrace] 9/14 xapi Called from file ocaml/xapi/export_raw_vdi.ml, line 116 May 23 16:40:37 xcp-mono02 xapi: [error||7644621 :::80||backtrace] 10/14 xapi Called from file ocaml/xapi/server_helpers.ml, line 101 May 23 16:40:37 xcp-mono02 xapi: [error||7644621 :::80||backtrace] 11/14 xapi Called from file ocaml/xapi/server_helpers.ml, line 122 May 23 16:40:37 xcp-mono02 xapi: [error||7644621 :::80||backtrace] 12/14 xapi Called from file lib/xapi-stdext-pervasives/pervasiveext.ml, line 24 May 23 16:40:37 xcp-mono02 xapi: [error||7644621 :::80||backtrace] 13/14 xapi Called from file string.ml, line 115 May 23 16:40:37 xcp-mono02 xapi: [error||7644621 :::80||backtrace] 14/14 xapi Called from file src/sexp.ml, line 113 May 23 16:40:37 xcp-mono02 xapi: [error||7644621 :::80||backtrace] Can anyone say anything about the cause of the problem or any ideas for further analysis?

      @olivierlambert said in Backup-NG Error "invalid header checksum" after VM-Disk-Resize and reaching retention Limit.: So the issue appeared just when the oldest extended delta had to be merged in the full I suppose. This is exact, but we need to have a proper process to reproduce it. This might be related to: increasing the size of the disk above a certain threshold increasing the content of the disk above a certain threshold
