Carbon Copy Cloner backups to T9-450 incredibly slow
Posted: 07 Mar 2024, 01:26
Hi there,
I bought a T9-450 for use as a remote backup for a Thunderbolt DAS attached to my Mac.
To do the initial backup which is very large (in the order of 45TB) I connected to the T9-450 via an OWC Thunderbolt to 10GBe adapter directly.
I can see the NAS fine and set up a separate user for the Backups with a visible public folder. I then configured CCC to backup to that folder.
That was very slow (about 7MB/s), so I read in the CCC documentation that backing up to a Sparse Image Bundle could improve the speed, but unfortunately it seemed to be even slower.
I have tried connecting via AFP rather than SMB which does seem a bit quicker, and I should say that just copying files is much quicker, in the order of 500MB/s.
I'm beginning to think that the T9-450 (or indeed any NAS) isn't really suitable for backups, especially when your files are a mixture of small and large as mine are. Do you have any tips to improve backup speed?
