Cache Option for Snapshot Build

Recommended Posts

Snapshot building is a time killer on large volumes.

 

 

 

It appears that there is an ACK for each individual file in the snapshot. That is what slows down the process, especially on the network.

 

 

 

One way to speed things up is to provide an option to cache the snapshot of, say, the first 10,000 files. Then write that block of snapshot data all at once.

 

 

 

That way both local and network snapshots would run many times faster. For network backups it would greatly reduce network traffic also.

 

 

 

With today’s fast media, the snapshot is becoming the bottleneck for backing up large volumes. This would speed up the process greatly.
