Hi,

I currently use dfdss for daily off-site ftp backups.

Currently I do the following:

• Use dfdss to dump the required datasets to dasd, then
• Use TSO transmit to create a portable version of the dump and finally,
• Copy the xmit file to an ftp server using binary ftp

The above steps work & allow dataset restoration but takes consideration space & CPU time.

Instead of all the above, I was wondering if z/OS 3.1 dfdss allows directly uploading/ restoring a logical dataset dump to & from a minio or other S3 cloud?

Thanks,

Travis 

Hi Travis, 

Do you have DS8900 storage?  DFSMSdss has the ability of creating your backups on an S3-compatible cloud or even TS7700 object storage using DS8K  (Transparent Cloud Tiering) TCT.  

Other clients have also attempted what you are wanting using CDA...there is a blogpost about it here: https://community.ibm.com/community/user/ibmz-and-linuxone/blogs/john-hogan/2024/05/06/using-gdkutil-to-copy-backup-tape-data-to-an-s3-co?communityKey=e7b7d299-8509-4572-8cf1-c1112684644f

I would be happy to have a call with you and talk about how to use TCT.  If you do not have DS8K storage or do not want to use TCT, we can still have a call and discuss roadmap items under an  NDA.

Thanks, 

Ernesto E. Figueroa

Hi Ernesto,

Thanks for your reply, sorry I just found it as I just realised outlook classified everything from IBM Communities as spam :(

For our production data, we use Dell Powermax 8000s; which from what I understand can't yet be used with TCT.

It'd be really great if DFDSS could upload directly to S3 storage  - should I create an IBM Idea?

I've had a play with GDKUtil & got it to upload / download small files to a local minio server.

I'll continue to pursue that option, as it looks like it might work with larger DFDSS dumps.

For example this is one of the dumps I'll try and upload to minio using gdkutil soon:

Hi Travis, I wanted to follow up with you on this topic.  

Please look at our DFSMSdss enhancement OA66450 shipped in 4Q25.    This is our direct-to-cloud support which leverages the latest DFSMSdfp Cloud Data Access (CDA) access method.

With this enhancement you can accomplish specifically what you are looking for in a single step for Dump.

I hope this helps!

Hi,

Thanks, I've managed to dump several data sets to our internal cloud servers:

I've noticed CDA is adding compression support in https://www.ibm.com/support/pages/apar/OA66536 ,

is there any future plans to allow compression with  DFDSS dump to cloud?

Thanks,

Hi Travis, 

Im glad you were able to use our new support and hope that the setup and invocation was fairly simple - especially since you had already used GDKUTILS.

As far as compression, you will be glad to hear that you will not have to wait very long.  Please review the 1Q25 announcements, here: https://community.ibm.com/community/user/ibmz-and-linuxone/blogs/fiona-king1/2025/02/18/zos-31-1q-2025-enhancements?communityKey=2eba32a4-9426-4331-81e7-8ea120e4fd99. Specifically under "DFSMS cloud object storage enhancements,"  for OA67394.

Hi Ernesto,

Thanks, I just got the PTF for OA67394 and was able to use the new CDACOMPRESS keyword :)
