Laserfiche Repository locking during backup

asked on November 14

Hello,

 

I have a user whose Laserfiche environment is run in a VM and doing backups with a product called Veem. Any time they perform a backup using Veem, the laserfiche repository locks up. Has anyone seen this behavior before? Are there any preferred settings for a Veem backup?

 

Thanks!

Hi Charles,

If I recall correctly, Veeam uses snapshot-based backups. It may be consuming all available disk I/O (or other system resources) during the snapshot process, causing the repository to "lock up". I would recommend setting up and running a Windows Performance Monitor Data Collector Set with the "System Performance" or "System Diagnostic" template and checking out the report for any obvious resource constraints. You could also set up a custom Data Collector Set to record the performance counters included with the Laserfiche Server and Full Text Search Engine.

Nothing to my knowledge. At the end of the day, Laserfiche stores all of its non-database application/repository information as normal files in Windows. I would start with performance monitoring and checking error logs to narrow down the root cause. Once you have a better idea on that front (say disk I/O constraints), you may be able to reconfigure Veeam to avoid causing the issue.

I'm curious about this, so please post an update if you identify the cause!

Samuel,

 

Thanks for the information! The end user was wondering if there might be some custom scripts, special processes or specific options within the Veeam software that Laserfiche recommends for Veeam to backup their product/servers.

 

They are stating that no other servers crash when Veem performs it's backups so they just want to make sure that their backup procedures coincide with what any guidlines Laserfiche may have for these types of backups.

 

Thanks!
