Clean Operations
The
all
option resets the
clean
operation to the default of 25% of space available for data.
filesys clean set amount {[[ n hrs][ n GB-free]] | all}
For example, to set the
clean
operation to run until 100 gigabytes are available for data:
# filesys clean set amount 100 GB-free
Set Network Bandwidth Used
To set
clean
operations to use a lower level of system resources when the restorer is busy, use the
filesys set throttle
operation. At a percentage of 0 (zero), cleaning runs very slowly or
not at all when the system is busy. A percentage of 100 allows cleaning to use system resources in
the usual way. The default is 100. When the restorer is not busy with backup or restore operations,
cleaning always runs at 100% (uses resources as would any other process). Administrative users
only.
filesys clean set throttle percent
For example, to set the
clean
operation to run at 30% of its possible speed:
# filesys clean set throttle 30
