Behavior on Attr Error
Description
Set the maximum bytes within a block that an ascp
receiver can write to disk. The default of zero causes
the Aspera receiver to use its default internal buffer
size, which may vary by operating system. This is a
performance-tuning parameter for an Aspera receiver
(which only takes effect if the receiver is a server).
Set the number of threads the Aspera sender uses to
read file contents from the source disk drive. It takes
effect on both client and server, when acting as a
sender. The default of zero causes the Aspera sender to
use its internal default, which may vary by operating
system. This is a performance-tuning parameter for an
Aspera sender.
Set the number of threads the Aspera receiver uses to
write the file contents to the destination disk drive. It
takes effect on both client and server, when acting as a
receiver. The default of zero causes the Aspera receiver
to use its internal default, which may vary by operating
system. This is a performance-tuning parameter for an
Aspera receiver.
Set the number of threads the Aspera sender uses to
scan directory contents. It takes effect on both client
and server, when acting as a sender. The default of zero
causes the Aspera sender to use its internal default.
This is a performance-tuning parameter for an Aspera
sender.
Set the number of threads the Aspera receiver uses to
create directories or 0 byte files. It takes effect on both
client and server, when acting as a receiver. The default
of zero causes the Aspera receiver to use its internal
default, which may vary by operating system. This is a
performance-tuning parameter for an Aspera receiver.
Set the number of threads the Aspera sender and
receiver use to delete files. This is a performance-
tuning parameter.
Set to true to enable sparse file checking, which
tells the Aspera receiver to avoid writing zero blocks
and save disk space. The default of false to tell
the Aspera receiver to write all the blocks. This is a
performance-tuning parameter for an Aspera receiver.
Set behavior for when operations attempt to set or
change file attributes (such as POSIX ownership,
ACLs, or modification time) and fail. Setting to yes
returns an error and causes the operation to fail. Setting
to no logs the error and the operation continues
