Performance impact of cloning

[bonsai]

Do you know how much of a performance impact there is on the source instance when a clone is performed?

I'm thinking of running clones consecutively with a few hours between each.

In that case, is there a risk of the performance of the source instance decreasing?

Hi @bonsai ,

1. Schedule Cloning During Off-Peak Hours:

   • Perform cloning during off-peak hours when the source instance has lower usage. This helps minimize the impact on users and ongoing operations.

2. Incremental Cloning:

   • If possible, use incremental cloning methods that reduce the amount of data transferred and minimize resource consumption.

3. Performance Testing:

   • Conduct performance testing before and after cloning to assess the impact and ensure that the source instance remains stable.

@bonsai ,

Below are performance issues that occur if you are cloning in business hours. so, schedule cloning during non-business hours.

1. Resource Utilization:

   • Cloning processes typically consume significant system resources, including CPU, memory, and I/O operations. This can lead to a temporary decrease in performance for the source instance as resources are diverted to handle the cloning process.

2. Database Locking:

   • During cloning, the database may experience locking or contention issues, which can affect the performance of ongoing transactions and queries.

3. Network Bandwidth:

   • Cloning involves transferring large amounts of data over the network. This can impact network bandwidth and potentially slow down other network-dependent operations.

If my response helped please mark it correct and close the thread so that it benefits future readers.

Hello @bonsai ,

There is zero impact on the source instance, because the clone is using the most recent backup of that instance, and not the live system.

When you request a clone you will get an email notification from Now Support that says something like "clone is based on backup taken on <timestamp>".

Regards,

Robert

I agree with both opinions, but is there any official information available?
