The XCP NFS estimate command is used to estimate the time to complete a baseline copy from the source to destination. It calculates the estimated time to complete a baseline copy by using all of the current available system resources, such as CPU, RAM, Network, and other parameters. You can use the -target option to start a sample copy operation and get the estimation time.

The following table lists the estimate parameters and their description.
| Parameter | Description |
|---|---|
Specifies the catalog name of a previous copy or scan index. |
|
Uses gigabits of bandwidth to estimate best-case time (default: 1). |
|
Specifies the target to use for live test copy. |
|
Specifies the duration of live test copy (default: 5m). |
|
Specifies the read/write block size (default: 64k). |
|
Specifies the request size for reading directories (default: 64k). |
|
Preserves access time of the file or directory (default: False). |
|
Sets the log level; available levels are INFO, DEBUG (default: INFO) |
