XSIBACKUP-FREE 11.2.9 slow NFS backup speed

I wonder what "High speed and deduplication is not available in XSIBACKUP-FREE" means in the header of the log file. Is the backup speed to an NFS resource limited to 10Mbs?
When I'm backing up to an NFS server, the network cards are 40GB Ethernet (tested - other data goes fast) but the maximum backup speed is only 10Mbps.

Re: XSIBACKUP-FREE 11.2.9 slow NFS backup speed

Backups made to local storage are always much slower than over IP backups. Reading, hashing and compression must be done with a single core as the (c)ESXi shell is limited that way. By using an IP backup host you allow the load to be distributed among the two ends.

If you need more speed than with (c)XSIBackup Classic, use new (c)XSIBackup-DC. It is a C monolithic binary and it offers native support for CBT (Changed Block Tracking) technology.

Still, even by using our latest edition, backups made over IP will be much faster than local backups.
