Workflow has been partially finished (VMware)

I have tried to get incremental backup for ESXi host. Full backup finished successfully. But incremental failed with error:
Store task failed: SyntheticBackupException: Command execution failed: [cp, -v, --reflink=always, /mnt/srv04/storware01/build-agent01__421ba2e0/mnt/srv04/storware01/vprotect_data/build-agent01__421ba2e0/build-agent01__Hard_disk_1-flat.vmdk/1701634963404, /mnt/srv04/storware01/build-agent01__421ba2e0/mnt/srv04/storware01/vprotect_data/build-agent01__421ba2e0/build-agent01__Hard_disk_1-flat.vmdk/1701720032667] Return code: 1 output: ['/mnt/srv04/storware01/build-agent01__421ba2e0/mnt/srv04/storware01/vprotect_data/build-agent01__421ba2e0/build-agent01__Hard_disk_1-flat.vmdk/1701634963404' -> '/mnt/srv04/storware01/build-agent01__421ba2e0/mnt/srv04/storware01/vprotect_data/build-agent01__421ba2e0/build-agent01__Hard_disk_1-flat.vmdk/1701720032667' ] error: [cp: failed to clone '/mnt/srv04/storware01/build-agent01__421ba2e0/mnt/srv04/storware01/vprotect_data/build-agent01__421ba2e0/build-agent01__Hard_disk_1-flat.vmdk/1701720032667' from '/mnt/srv04/storware01/build-agent01__421ba2e0/mnt/srv04/storware01/vprotect_data/build-agent01__421ba2e0/build-agent01__Hard_disk_1-flat.vmdk/1701634963404': Operation not supported ].

P.S.: what "SyntheticBackupException: This export strategy doesn't support Synthetic backups" means for XCP-ng incremental backup? Full backup is working.

Hello!
Thank for your post.

It looks, like you created Synthetic Backup Destination on file system, which not support it. We use XFS as synthetic file system.

You could use classic File System, or recreate Backup Destination on XFS file system.

Kindly regards

Thanks for the information. I'll try to recreate backup storage. But as I thought the NFS 4.2 is also supported as destination for synthetic backups.
I have mounted share:
172.16.16.13:/mnt/seagate_4tb/storware01 on /mnt/srv04/storware01 type nfs4 (rw,relatime,vers=4.2,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=172.16.16.104,local_lock=none,addr=172.16.16.13)

May be you can tell something about XCP-ng "export strategy" error? Thanks.

Hi! @user

NFS4.2 have support to synthetic backup, but it is necessary to use XFS under NFS share. NFS only provide possibility to use synthetic file system under share, we support XFS as Synthetic FS.

The same error you have in XCP-ng.
