Some minimalist Linux distributions (such as Alpine Linux) use an older version of Busybox, which misses the `--preserve-status` option on the `timeout` command.

### Database disk image is malformed
This error has been observed mostly when Gravity Sync is running on slower SD Cards or older Raspberry Pi systems, and where the backup of the running Domain Database takes longer than expected (or never finishes) and thus when Gravity Sync replicates that copy to the secondary, it's malformed.
