Need help on rsync
Hi experts,
We need copy 5TB data from one server to another (over a 10Gbps link). We plan to use rsync -av remote:/<path /local on destination server but there're few special requirements like:
1. data copy process should run only from 18:00 Hrs to 07:00 every day until copy is completed. Is it a good idea to cron 2 jobs - one of them starts script at 18:00 and the other kills it at 7:00?
2. log should be emailed once in every 60 minutes. I noticed there're lot of redundant unnecessary info in the logs. is there any filter?
3. can transfer speed be controlled? (to reduce a bit so that it won't choke entire bandwidth)
4. rsync version on destination machine is 3.0.6. yum update rsync says this is final version.
5. I think there's no need for rsync daemon just standalone command would suffice. please confirm.
Please advise, Many thanks!!

rdf::query::plan::service
RDF::Query::Plan::Service(3pm) User Contributed Perl Documentation RDF::Query::Plan::Service(3pm)
NAME
RDF::Query::Plan::Service - Executable query plan for remote SPARQL queries.
VERSION
This document describes RDF::Query::Plan::Service version 2.908.
METHODS
Beyond the methods documented below, this class inherits methods from the RDF::Query::Plan class.
"new ( $endpoint, $plan, $silent, $sparql, [ \%logging_keys ] )"
Returns a new SERVICE (remote endpoint call) query plan object. "<$endpoint"> is the URL of the endpoint (as a node object). "<$plan">
is the query plan representing the query to be sent to the remote endpoint (needed for cost estimates). "<$sparql"> is the serialized
SPARQL query to be sent to the remote endpoint. Finally, if present, "<%logging_keys"> is a HASH containing the keys to use in logging
the execution of this plan. Valid HASH keys are:
* bf - The bound/free string representing C<<$plan>>
"new_from_plan ( $endpoint, $plan, $context )"
Returns a new SERVICE query plan object. "<$endpoint"> is the URL of the endpoint (as a string). "<$plan"> is the query plan
representing the query to be sent to the remote endpoint. The exact SPARQL serialization that will be used is obtained by getting the
originating RDF::Query::Algebra object from "<$plan">, and serializing it (with the aid of the RDF::Query::ExecutionContext object
"<$context">).
"execute ( $execution_context )"
"next"
"close"
"endpoint"
"sparql"
Returns the SPARQL query (as a string) that will be sent to the remote endpoint.
"lhs"
"silent"
Returns a boolean value indicating whether the service plan will ignore errors.
"pattern"
Returns the query plan that will be used in the remote service call.
"distinct"
Returns true if the pattern is guaranteed to return distinct results.
"ordered"
Returns true if the pattern is guaranteed to return ordered results.
"plan_node_name"
Returns the string name of this plan node, suitable for use in serialization.
"plan_prototype"
Returns a list of scalar identifiers for the type of the content (children) nodes of this plan node. See RDF::Query::Plan for a list of
the allowable identifiers.
"plan_node_data"
Returns the data for this plan node that corresponds to the values described by the signature returned by "plan_prototype".
"graph ( $g )"
"explain"
Returns a string serialization of the query plan appropriate for display on the command line.
