If you’re reading this blog, you know that Holland Backup Manager is an easy and efficient way to configure backups. Most of the issues I have experienced are user errors, specifically how I configured the backups. The following error is one such example:<\/p>\n\n\n\n
[ERROR] Insufficient Disk Space. 1.10TB required, but only 755.42GB available on \/backups<\/em><\/p>\n\n\n\n At first glance, the obvious solution is to add more disk space, but my compressed backups were 600GB. There is enough disk space. Why did the backup fail if it had enough disk space?<\/p>\n\n\n\n The answer lies within the first part of \/var\/log\/holland\/holland.log.<\/p>\n\n\n\n Here, Holland Backup Manager is adjusting the estimated size by 50% to 1.1TB. This estimation is controlled by the Holland configuration option, estimated-size-factor. It specifies the scale at which Holland will decide if there is enough disk space for the backup file. After Holland 1.1.1, this will be the default if Holland cannot estimate the backup size based on previous ones.<\/p>\n\n\n\n This error occurred on a new server running Holland Backup Manager 1.1.10. My only explanation for Holland defaulting to the estimated size factor is that there was not enough historical data for the estimation.<\/p>\n\n\n\n The fix was as simple as changing the value in the Holland backupset configuration files.<\/p>\n\n\n\n Now, the backup successfully starts since Holland has decided there is enough disk space.<\/p>\n\n\n\n Visit Holland Backup Manager’s website<\/a> for a list of available options.
