Urbackup client for Hyper-V with ZFS backend : invalid character '[' in name

Hello,

I am using the lastes stable release of UrBackup client for Hyper-V.
My server is v2.5.31 running on Linux debian v11 (kernel 5.15.107)
I am using ZFS backend.

I installed the latest stable release of Hypoer-V client and I get the following errors:
Cannot create directory /zpool/backup/urbackup/SRV64304HV[VM64304Q]/230710-0303 for backup (server error). cannot create ‘zpool/backup/files/SRV64304HV[VM64304Q]/230710-0303’: invalid character ‘[’ in name

None of the virtual clients in Hyper-V is able to start backup.

Ping?

Will revert to non-hyperv client manually deployed in each VM, but still interested in hyper-v client for future deployments if it gets fixed.

Keep up good work, UrBackup rocks!
