corrupted ibdata

hi all,

i’ve recently started using xtrabackup for mysql, i run the backup on my slave db. i have a staging server where i restore the backup i created on slave daily, it was working fine until 4 days ago, every time i restore i get the errors:

InnoDB: is in the future! Current system log sequence number 373492778508.
InnoDB: Your database may be corrupt or you may have copied the InnoDB
InnoDB: tablespace but not the InnoDB log files

there has been no changes on DB config just wondering why this is happening, any idea? will truly appreciate all the help.
