Corrupt bamboo backup

[Sivaz]

Hi, Our current bamboo scheduled backups fail when trying to export the AUTH_ATTEMPT_INFO table into loginInfos.xml.

What is this table meant for? I notice that any invalid login attempt is being logged into this table. But you could also for testing purposes enter incorrect or non ascii characters. Especially while doing security audit of application there could be various attempts to login with invalid user names, e.g. '"\'\");|]*{
<>.

With such a data, the backup seems to fail at com.ctc.wstx.exc.WstxIOException: Invalid null character in text to output

I would like to know how this table is used, and if its OK to manually delete such records from the DB directly so that my scheduled backups would work.

Thanks.

BUMP ^

Issue still exists in 5.9.9

Incorrectly formed REST request would result in bad entry to AUTH_ATTEMPT_INFO, which will fail the next backup.

I deleted the entries from the table, then the backup worked. But the backup process should have been able to still process the backup even with such characters.
