Do you get the same option for DTACPR on the SAV command Rob?

Cheers

There are some pretty impressive compression options on the SAV* commands
themselves.
Maybe I'm only used to current versions of the software but check this
out:
SAVLIB LIB(ROB) DEV(TAPVRT01) DTACPR(*ZLIB)

Ok, this is what I did in the end.

Scenario:

Did a complete restore from SYS A to SYS B
Started conversion to 7.5 on SYS B
Kept on working on SYS A

The question was how to synchronize A to B for the changes that happened
in the mean time.

The solution I used was the following:

* Do a DSPOBJD of all objects in an outfile.
* Find all the objects that changed after date X
* Collected all the libraries that needed to be synced
* Used SAVRSTCHG for each library to sync the changes (with print
output)
* Transferred the printed output of all jobs to a file
* Used some regex scanning for issues
* Fixed the issues that arose

* For the IFS I used SAVRST for the directories that we change. E.g.
/home

In the end, it could all be handled by the object connect function and
some elbow grease:

Yes, that would work, however, the image catalog object is not
compressed.

To save FTP time, after you save the objects to the Virtual Tape, save
the
virtual tape file to a standard *SAVF with compression Medium. We have
found Medium is the best bang for the time spent compressing and we have
seen as good as 70% compression rates.

Example - if you have a virtual catalog as created below:

|CRTIMGCLG IMGCLG(MYCATALOG) DIR('/MYCATALOGDIRECTORY') CRTDIR(*YES)
ADDVRTVOL(1) PREFIX(ABC) IMGSIZ(100000) TEXT(catalog-description)
TYPE(*TAP)|


CRTSAVF QGPL/MYCATALOG TEXT('MY COMPRESSED SAVE')

SAV DEV('/QSYS.LIB/QGPL.LIB/MYCATALOG.FILE')
OBJ('/MYCATALOGDIRECTORY/ABC01') DTACPR(*MEDIUM)

(FTP QGPL/MYCATALOG to the new system)
(Un-compress)

RST ('QSYS.LIB/QGPL.LIB/MYCATALOG.FILE) OBJ('/MYCATALOGDIRECTORY/ABC01')

Hi,

Two weeks ago, we did a complete system save and restore on our new
cloud
partition. The thing is configure and now I want to get the changed
objects
there.

Since I have no tape device there, I was thinking of creating a virtual
tape as described herehttps://
www.ibm.com/docs/en/i/7.3?topic=media-virtual-tape

Then do a savchgobj *allusr to that tape, get the image catalog to the
other machine, and restore the objects.

Is this the correct workflow?

Cheers, Wim
