FTP

Edit online

You can configure File Transfer Protocol (FTP) storage.

About this task

Note the following guidelines for using FTP storage and then provide the storage information as follows:

  • Use a high-performance computer as the FTP server, especially those with fast disk read and write speed.
  • Use a high-level port as the port of the FTP server, such as a port after 6000, to prevent other software installed on the FTP server from occupying the same port and affecting the data being uploaded and downloaded.
  • Only the passive mode of an FTP device is supported.
  • Do not support the FTP device to enable SSL/TLS. If you need high-level data transmission security and encryption, you can use the Secure File Transfer Protocol (SFTP) service instead. IBM® Storage Protect for Cloud Microsoft™ 365 also supports using SFTP devices. You can contact the IBM Software Support team for assistance.
  • If the FTP server you want to use is in an internal network environment and there is a firewall between the internal network and external network, ensure all the ports (the connection port and all the ports in the dynamic port range of the FTP server) can pass through the firewall.
  • If the FTP server has set access control using IP addresses, you must download the reserved IP addresses from the IBM Storage Protect for Cloud Microsoft 365 interface and add them to the firewall’s allow list. For detailed instructions, refer to Download a List of Reserved IP Addresses.

Procedure

Follow the instructions below:
  1. Storage Type – Select FTP from the drop-down list.
  2. Host – Enter the IP address or name of the FTP server.
  3. Port – Enter the port to use to connect to this FTP server. The default port is 21.
  4. Username – Enter the username to use to connect to this FTP server.
  5. Password – Enter the password of the specified username.
  6. Extended Parameters – Enter the following extended parameters if necessary. If you have multiple parameters to enter, press Enter on the keyboard to separate the parameters. Refer to the instructions below to add parameters:
    • IsRetry – Whether or not to try again when IBM Storage Protect for Cloud failed to write the data in the physical device.
      • If you enter IsRetry=true, it will try again when IBM Storage Protect for Cloud failed to write the data in the physical device.
      • If you enter IsRetry=false, it will not try again when IBM Storage Protect for Cloud failed to write the data in the physical device.
    • RetryInterval – Customize the retry interval when the network connection is interrupted. You are allowed to enter any positive integer between 0 and 2147483646 (the unit is second). For example, RetryInterval=30 means that it will try to reconnect every 30 seconds.

      If you do not configure this parameter, the value is 30 seconds by default.

    • RetryCount – Customize the reconnection times after the network connection is interrupted. You are allowed to enter any positive integer between 0 and 9. For example, RetryCount=9 represents when the network connection is interrupted, it can reconnect at most 9 times.

      If you do not configure this parameter, the value is 6 by default.
