Large File Transfers
Frequently Asked Questions

The state email systems will accommodate messages under 20MB in total size. Attachments can grow somewhat when formatted for email transport, so the effective limit may actually be smaller than 20MB. Other email systems may have smaller message size limits. ETS offers three options for transferring larger files:

HTTPS drop-off and pick-up using ZendTo

For ad-hoc file transfers between humans, look to drop.state.ak.us. The application accepts uploaded files and sends one-time links to these files for download by email. To use this service, point your web browser at https://drop.state.ak.us/drop

Authenticated State of Alaska users may:

  • Upload files and have those links sent by email to anyone.
  • Create an upload-request which can be sent by email to anyone.
  • Download files which have been left for them.

Unauthenticated users may:

  • Upload files and have those links sent to @alaska.gov email addresses.
  • Download files for which they have the confirmation code.

By default, notification emails are sent to the uploader when files are downloaded. Files may be removed by the uploader and are automatically removed from the server after four days.

Cons:

  • The service is not suitable for automated processes.
  • Transfer is somewhat slower than FTP.
  • Files are not encrypted while stored.
  • Is limited to files of 8GB or smaller.
  • Support for files larger than 2GB is limited by your operating system and web browser.

Pros:

  • Is available to all authenticated State of Alaska users
  • Works (for files smaller than 2GB) in all common web browsers


Authenticated FTP

Authenticated ftp accounts are available for specific business requirements, usually for automated processes with business partners which cannot support other mechanisms. To request an FTP account, create a new 'request' in Service Desk.

Cons:

  • Their use of clear-text passwords constitute a violation of security policy.
  • Files are transported unencrypted across the network which is incompatible with some business requirements.
  • Files are not encrypted while stored.

Pros:

  • Client software is easiliy available, and common operating systems and web browsers natively support ftp.
  • Can handle very large files.


Authenticated FTPS

Authenticated accounts on an ftps server are available for specific business requirements, usually for automated processes with business partners which will not support other mechanisms. To request an FTPS account, create a new 'request' in Service Desk.

Cons:

  • Files are not encrypted while stored.
  • Client software is not part of common operating systems or web browsers.
  • Can handle very large files.

Pros:

  • Files and passwords are encrypted in transit

Note: This service uses FTPS. ETS does _not_ offer SFTP service.
