How to Upload a Dump File

(These upload directions also apply to other large files, such as requested disk images.)

If you need information on how to create a dump file, read this page. Always provide a testlog log file from the system that was taken in the exact configuration as the system dump. Normally you will attach the testlog log file to your ticket at the same time you upload your dump file. If in doubt when to capture a matching testlog log file, do it immediately after rebooting after the trap. More information on how to create a testlog log file is here.

Zipping the dump file using 7zip

7zip (or p7zip) is a highly efficient compression program. ArcaOS ships with Archive Tool, which can create and expand 7zip files. Zippy, available in the Arca Noae store, can also handle these files. Alternatively, Arca Noae Package Manager may be used to install the p7zip package to manipulate 7zip archives from the command line. 7zip is recommended over zip due to its greater efficiency.

  • Choose a file name for the zipped archive file you are going to upload. Your archive file name should contain the date and the ticket number. For example, if your ticket number was 2011 and today’s date was March 12, 2018, your archive file name would be:

    If you need to upload more than one dump on the same date, add a number to the end of the file name:

  • Zip the dump file. This example assumes your dump file is still on your dump partition and that your dump partition is drive letter o: and the archive file name is as described above.

Uploading the dump file

  • If using a command line FTP client, be sure to start this process from the directory in which the 7z archive file is located. This is because you must not specify a path for the 7z archive or the FTP upload will fail.
  • Upload the 7z archive file to the Arca Noae FTP server ( The login credentials are:
    Password: <Your email address>
    Note that this is a write-only login. You will not be able to read files, do directory listings, delete files, or rename files on the FTP server. You also cannot upload the same file name more than once. If you need to re-upload a file (because of an error, etc.) then rename your file as shown in the examples above and upload using the new file name.
  • WARNING: Make sure you upload the 7z file name only. DO NOT specify a path.
  • Example:
