make_sys_image determine size prior to creating image

[OFC_EDM]

How can I determine the size of a make_sys_image prior to the actual creation of the image?

This is what I thought would tell me the size but I don't see the info.

make_sys_image -p \
-s local -d /var/tmp/image/archives \
-n rp4440_archive.gz

Dear Kevin,

Alternatively you can calculate the tottal data that you want to make it as a image, by using #bdf and summing up the used space.
You can expect the image size to be 70% of this tottal data size.

make_sys_image just uses #tar utility to take the backup and makes a archive using gzip.

With Regards,

Siva.

The preview (-p) option does not check the actual archive size for you. More what it does is do the check for the destination source. (Is it reachable?) Then it just looks (I think) cursorily at the syntax/options/etc for the make_sys_image level you are running to make sure it's ok. Then the process ends.

I don't know that there is a tool in ignite that previews the space based on what you want in the archive. I suspect it would be an enhansement to the product in the future. I wonder who else would think it would be a nice thing to have. I think it would be a good thing...
