Snapshot migrate issues

Hello,

Kopia snapshot migrate… is an amazing feature to replicate snapshots between repositories/ locations…

However it appears to be very time consuming running migrate in pull mode… Haven’t tried push mode…

I have 2 repositories one on my Nas and another one on a USB HDD. The Nas repositories have snapshots of qcow2 images (snapshots size ~ 380G - 400G. These are large qcow2 files ~60G. Both repositories are compressed zstd best comp.

I am doing a snapshot migrate Nas -->> usb… Over WiFi

The real problem comes if I terminate kopia in the middle say when it’s hashed arround 250G…
Repeating the same command will start again, redownloading & rehashing without uploading till it reaches the place where I terminated kopia previously.

The whole process of redownloading from my Nas and rehashing already partially migrated snapshots takes time…

The same issue appears for snapshot create on large files…
