Dear Experts,
I would like to know what's the best method for copy data around 3 mio (spread in a hundred folders, size each file around 1kb) between 2 servers?
I already tried using Rsync and tar command. But using these command is too long.
Please advice.
Thanks

Hi Experts,
I've been asked if there is a fast way to duplicate a file(10GB) and zip it at the same time. The zipped file would be FTP'd.....management is asking this. Maybe there is a better method all together? any ideas? CP will not cut it.

PG_TEST_FSYNC(1) PostgreSQL 9.2.7 Documentation PG_TEST_FSYNC(1)
NAME
pg_test_fsync - determine fastest wal_sync_method for PostgreSQL
SYNOPSIS
pg_test_fsync [option...]
DESCRIPTION
pg_test_fsync is intended to give you a reasonable idea of what the fastest wal_sync_method is on your specific system, as well as
supplying diagnostic information in the event of an identified I/O problem. However, differences shown by pg_test_fsync might not make any
difference in real database throughput, especially since many database servers are not speed-limited by their transaction logs.
OPTIONS
pg_test_fsync accepts the following command-line options:
-f, --filename
Specifies the file name to write test data in. This file should be in the same file system that the pg_xlog directory is or will be
placed in. (pg_xlog contains the WAL files.) The default is pg_test_fsync.out in the current directory.
-s, --secs-per-test
Specifies the number of seconds for each test. The more time per test, the greater the test's accuracy, but the longer it takes to run.
The default is 2 seconds, which allows the program to complete in about 30 seconds.
-V, --version
Print the pg_test_fsync version and exit.
-?, --help
Show help about pg_test_fsync command line arguments, and exit.
