The log is attached as mbackup_prepare_1.log
Backup dirs before any attempts to prepare are stored here:
ftp://ftp.askmonty.org/public/mdev18194/
backup_0 is the initial full backup.
backup_1 is the incremental backup.
To reproduce, unpack the backups and run
bin/mariabackup --prepare --apply-log-only --innodb-file-io-threads=1 --target-dir=backup_0 --user=root
|
bin/mariabackup --prepare --apply-log-only --innodb-file-io-threads=1 --target-dir=backup_0 --incremental-dir=backup_1 --user=root

Notes on the origin of the report. Please be aware it's not easily reproducible the same way, the test is concurrent by nature, and apparently there is a race condition involved.
The problem initially happened by running the concurrent test with MariaBackupIncremental scenario:

The test performs the following steps:
- start the server with
"--no-defaults" "--basedir=/home/travis/server/10.4" "--lc-messages-dir=/home/travis/server/10.4/share" "--character-sets-dir=/home/travis/server/10.4/share/charsets" "--tmpdir=/home/travis/logs/vardir2/tmp" "--core-file" "--datadir=/home/travis/logs/vardir2/data" "--max-allowed-packet=128Mb" "--port=19300" "--socket=/home/travis/logs/vardir2/mysql.sock" "--pid-file=/home/travis/logs/vardir2/mysql.pid" "--general-log" "--general-log-file=/home/travis/logs/vardir2/mysql.log" --log_output=FILE --max-statement-time=20 --lock-wait-timeout=10 --loose-innodb-lock-wait-timeout=5 --loose-debug_assert_on_not_freed_memory=0 --innodb-encrypt-tables --innodb-encrypt-log --innodb-encryption-threads=4 --aria-encrypt-tables=1 --encrypt-tmp-disk-tables=1 --file-key-management --file-key-management-filename=/home/travis/mariadb-toolbox/data/keys.txt --plugin-load-add=file_key_management - run concurrent DML/DDL flow on the server;
- after ~1 min, take the full backup from the running server:
bin/mariabackup --backup --target-dir=/home/travis/logs/vardir2/backup_0 --protocol=tcp --port=19300 --user=root(succeeded, the log attached as mbackup_backup_0.log
; - after another ~1 minute, run the incremental backup as
bin/mariabackup --backup --target-dir=/home/travis/logs/vardir2/backup_1 --incremental-basedir=/home/travis/logs/vardir2/backup_0 --protocol=tcp --port=19300 --user=root(succeeded, the log attached as mbackup_backup_1.log
; - after another ~1 minute, run the incremental backup again as
bin/mariabackup --backup --target-dir=/home/travis/logs/vardir2/backup_2 --incremental-basedir=/home/travis/logs/vardir2/backup_1 --protocol=tcp --port=19300 --user=root(succeeded, the log attached as mbackup_backup_2.log
; - let the test flow continue for a little while
- shut down the server gracefully (succeeded, the error log is attached as mysql.err_orig;
- run mariabackup --prepare on the full backup as
bin/mariabackup --prepare --apply-log-only --innodb-file-io-threads=1 --target-dir=/home/travis/logs/vardir2/backup_0 --user=root(succeeded, the log attached as mbackup_prepare_0.log
; - run mariabackup --prepare on the first incremental backup as
bin/mariabackup --prepare --apply-log-only --innodb-file-io-threads=1 --target-dir=/home/travis/logs/vardir2/backup_0 --incremental-dir=/home/travis/logs/vardir2/backup_1 --user=root(failed, the log is attached as mbackup_prepare_1.log
.
I have no information yet whether the problem happens on 10.1.
