I was experimenting with iMazing doing backups to my old Zyxl Nas542.
I did tests with AFP, SMB and NFS. Everything was dead slow.
After a while I found out the SMB performance on the Mac is low but could be fixed by setting
[default]
signing_required=no
in a newly created
sudo vi /etc/nsmb.conf
and a reboot of the Mac.
I got 116Mb/s for write and 75Mb/s for read on SMB3. Before write performance was at 2,5Mb/s
Anyway, as the Backup writes a lot of small files and folders performance didn't improve on either protocol.
75GB Backup took still several hours.
So I gave up.
This morning I created a growable disk image (sparseimage) on the SMB mount with AFPS format. Then tried to create a backup there and the first backup finished in about 45min for 75GB.
Subsequent backups didn't finish before too, now finish in about 10min.
So is there anything I should be aware of using sparseimage for backup or is there anything else better to improve the backup to then as?
