I have been using innobackupex for a while on a number of databases, but today I faced an issue which I haven’t seen before.
During initial backup of 470Gb MySQL database innobackupex fails with the following error:
I tried to make a backup on a local disk, on nfs mount and using nc. I tried to do it in tar.gz, tar and raw files.
Every time it failed somewhere at the end of the backup process, because resulted files are almost the same size as an initial ones.
Appreciate any help there.
