xtrabackup55 incremental support for raw disk partitions (raw devices)


I try to find a solution for incremental backup on a mysql 5.5 innodb engine that use a raw disk partition for my database.

This is my configuration from my.cnf read by the tool:

xtrabackup: innodb_data_home_dir =
xtrabackup: innodb_data_file_path = /dev/sdb:200Graw

[01] Copying /dev/sdb to /root/xtrabackup_backupfiles/sdb
[01] …done

log scanned up to (18032549002)

command used:

innobackupex --user=xxxxx --password=xxxxx /tmp
xtrabackup --backup

Unfortunately the data from /dev/sdb raw disk is not saved.

Does xtrabackup tool support this kind of backup?

What command should be used in this case?

Thank you!
