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.

regard,
Nhadie
