IBM Aspera HST Admin Manual page 240

mtime may be specified in any one of the following ways:
• As a positive number of seconds since 1970-01-01 00:00:00, for Unix and POSIX-compliant
operating systems.
Note: Some file servers, such as Windows NT, use a different epoch for the recursive modified
time. In this case, MTIME should be specified as a duration relative to present or UTC
timestamp.
• As a UTC timestamp with the format YYYY-MM-DDTHH:MM:SS, such as
2015-01-01T08:00:00.
• As a duration formatted as DDd HH:MM:SS or WWw DDd HHh MMm SSs. Directories whose
"mtime" is older than Now minus MTIME are not scanned. Input requirements: Leading zero
fields and spaces may be omitted. The leftmost fields are optional, but fields to the right of the
largest unit specified are required. For example, to exclude directories older than 24 hours, you
could specify 1d 0:0:0, 24:00:00, or 24h 00m 00s, but not 1d.
This option does not apply to the root directory.
Note: Aspera Sync stops and returns an error if the first run of async and the next run do not
use the same --exclude-dirs-older-than option. If the first run specifies --exclude-
dirs-older-than, then the next run must use this option, too. If the first run does not include
--exclude-dirs-older-than, then the next run fails if this option is specified.
-G size, --write-block-size=size
Use the specified block size for writing. size is an integer with units of K, M, or bytes. Default: 64
MB.
-g size, --read-block-size=size
Set block size for reading. size is an integer with units of K, M, or bytes. Default: 64 MB.
-H val, --scan-intensity=val
Scan at the set intensity. val can be vlow, low, medium, high, or vhigh. vlow minimizes
system activity. vhigh maximizes system activity by continuously scanning files without rest.
Default: medium.
--host=host
Synchronize with the remote host that is specified by hostname or IP address. If the remote host is
a cluster, enter the cluster DNS. When using --host=, the characters "@" and ":" are not treated
specially in the argument to -r or --remote-dir. The transfer username cannot be specified as
part of the remote directory filepath. Instead, it must be set with --user= or in the environment
variable $user (on Windows, %USER%). Allowed forms are as follows:
--remote-dir user@host:/rdir # (old method)
--user user --remote-dir host:/rdir
--user user --host host --remote-dir /rdir
--remote-dir host:/rdir
--host host --remote-dir /rdir # (uses $user)
The following means the same as the first three lines above:
-r /rdir --user=user --host=host
For backward compatibility, -r A:/rdir for any single letter A is still taken as a Windows path,
not as --host A -r /rdir. To specify a one-letter host name A, use an explicit --host=A.
-I file, --include-from=file
Scan and include paths specified in the filter file. For more information, see
Filtering Rules
-i file, --private-key-path=file
# (uses $user)
