We use Arcserve UDP 6.5 backup to backup our SQL server 2014. Backup of the database is successful but we could not perform truncation of the logs using the backup software.
The backup software shows that the logs are truncated but the database logs clearly show that the truncation did not happen.
The database permissions given to this domain account are sysadmin and we could use this account to performe a manunal truncation.
Arcserve could not find a reason for the log truncation failure.
