7zip vs 7zip engine compression issue

Got an error while trying to backup a SQL AWS RDS database and it threw an error while trying to compress it , it said “System error - Not implemented” - This happened when i chose the option “7zip (engine)”

8:30:01 PM : ERROR: Failed to backup “TestDB” database with “Full” backup type: 7-zip archiver error. > System ERROR: Not implemented

What is the different between “7-zip (engine)” v.s. regular “7-zip” ?

If “7-zip(engine)” is non-working when choosing AWS RDS SQL backups - then why is it there for selection - shouldn’t it be grayed out or not option when AWS RDS backup is chosen??

Note: it worked correctly when i chose the regular “7-zip” compression.

This was taken care of.
I mistakenly added a command that was meant for 7zip and not for zip.
error went away after removing the command in the additional options.

Hi Luis,

Good news! Thank you for the update.
