Description:
Backup tests (in backup and backup_engines suites) assume that the value of @@datadir is $MYSQLTEST_VARDIR/master-data/ and that @@backupdir equals @@datadir. This will trigger problems if one of these assumptions becomes false, e.g. because of changes in the testing framework.

It is possible and easy to write these tests so that they use the real value of @@datadir and @@backupdir and don't need these assumptions.

How to repeat:
Read test cases.

Suggested fix:
Instead of:

 --remove_file $MYSQLTEST_VARDIR/master-data/test.bak

use this:

 let $bdir=`SELECT @@backupdir`;
 --remove_file $bdir/test.bak

Thank you for the report.

Verified as described. Indicated code exists only in backup_errors.test

I think $MYSQLTEST_VARDIR/master-data/ is used in many other backup tests. For example in the main backup.test.

      BUG#40849. Most of the backup tests are replced to use 
      BACKUPDIR=`select @@backupdir` instead of using DATADIR.
      This will help in reducing the tests fail when there are changes
      in assumptions for usage of datadir.

      BUG#40849.Most of the backup tests from suite are replaced to use BACKUPDIR instead of using DATADIR.
      This will help in reducing tests fail when there will be chnages in assumptions for usage of DATADIR.
