Hello cafahag,

Thank you for using Acronis Corporate Products

Please make sure the User account on the NAS, under which you are trying to backup to it, belongs to the administrator group. Administrator group should also belong to Read/Write group.

Also, set backup archive splitting to 2 GB. NAS buffer may overflow if the files are larger than 2 GB.

Try setting Archive splitting in Acronis True Image to 2 GB:

1. Click "Tools" and select "Options";
2. Click "Archive splitting" and set the size to 2 GB.

Thank you.
