Hi,

Is it safe to remove the following files from MySQL data directory after successful backup:

xtrabackup\_binary  
xtrabackup\_binlog\_info  
xtrabackup\_binlog\_pos\_innodb  
xtrabackup\_checkpoints  
xtrabackup\_logfile

Regards

Some of those files are used to restore the backup or to make incremental backups for example.

xtrabackup\_checkpoints will store the LSN range of this backups. It is used for incremental backups…  
xtrabackup\_binlog\_info will contain the the bin log file and position when you made the backup. It will be useful if you want to create slaves from this backup  
xtrabackup\_binlog\_pos\_innodb if the same as xtrabackup\_binlog\_info but only valid if you only have XtraDB of InnoDB tables.  
xtrabackup\_binary xtrabackup used to make the backup.  
xtrabackup\_logfile used to restore your backup.

I don’t understand why you might want to remove those files from a backup… but not… this is not recommended.

Bye

Hi,

Thanks for reply.

Basically I’ve restored slave server with Xtrabackup script. I’m not planning to use it any more on these server so I though I’ll clean out these files from MySQL data directory.
