Rsync will skip any files that are already in the destination by default it uses file size+date+time or with the -c option computes a checksum.
--partial saves a partially transfered file and will resume from where it was, without this, a file that is in being transfered when a server is rebooted or goes off the network will be deleted and the file re-transfered. This can be important if large files are being transfered and starting again will waste a lot of bandwidth.
--del can be important to remove files on the destination side that don't exist on the source side.
Try is something like this to copy a directory path keeping owner/permissions and removing and file in dest not in source
also consider something like --bwlimit=4000 to avoid swamping your network by limiting the transfer to 4Mbps.
Hi Experts..
Could anyone please let me know the easier way to copy large dump of files from one server to another. I am trying to copy a set of dump files on two different servers placed in different geographic locations.. Though there are other factors such as latency, etc., slowing up the... (4 Replies)
Hi
I have a job that will be running nightly incremental backsup of a large directory tree.
I did the initial backup, now I want to write a script to verify that all the files were transferred correctly. I did something like this which works in principle on small trees:

I want to backup all the directory tress, including hidden directories, without copying any files.
find . -type d gives the perfect list.
When I tried tar, it won't work for me because it tars all the files.
find . -type d | xargs tar -cvf a.tar
So i tried rsync.
On my own test box, the... (4 Replies)

Possibly a dumb question, but I'm deciding how I'm going to do this. I'm currently rsyncing a 25TB directory (with several layers of sub directories most of which have video files ranging from 500 megs to 4-5 gigs), from one NAS to another using rsync -av. By the time I need to act ~15TB should... (3 Replies)

reboot
reboot(1M)reboot(1M)NAME
reboot - restart the operating system
SYNOPSIS
/usr/sbin/reboot [-dlnq] [boot_arguments]
The reboot utility restarts the kernel. The kernel is loaded into memory by the PROM monitor, which transfers control to the loaded kernel.
Although reboot can be run by the super-user at any time, shutdown(1M) is normally used first to warn all users logged in of the impending
loss of service. See shutdown(1M) for details.
The reboot utility performs a sync(1M) operation on the disks, and then a multi-user reboot is initiated. See init(1M) for details. On
systems, reboot may also update the boot archive as needed to ensure a successful reboot.
The reboot utility normally logs the reboot to the system log daemon, syslogd(1M), and places a shutdown record in the login accounting
file /var/adm/wtmpx. These actions are inhibited if the -n or -q options are present.
Normally, the system reboots itself at power-up or after crashes.
The following options are supported:
-d Force a system crash dump before rebooting. See dumpadm(1M) for information on configuring system crash dumps.
-l Suppress sending a message to the system log daemon, syslogd(1M) about who executed reboot.
-n Avoid calling sync(2) and do not log the reboot to syslogd(1M) or to /var/adm/wtmpx. The kernel still attempts to sync
filesystems prior to reboot, except if the -d option is also present. If -d is used with -n, the kernel does not attempt to
sync filesystems.
-q Quick. Reboot quickly and ungracefully, without shutting down running processes first.
The following operands are supported:
boot_arguments An optional boot_arguments specifies arguments to the uadmin(2) function that are passed to the boot program and kernel
upon restart. The form and list of arguments is described in the boot(1M) and kernel(1M) man pages.. If the arguments are
specified, whitespace between them is replaced by single spaces unless the whitespace is quoted for the shell. If the
boot_arguments begin with a hyphen, they must be preceded by the -- delimiter (two hyphens) to denote the end of the reboot
argument list.
Example 1: Passing the -r and -v Arguments to boot
In the following example, the delimiter -- (two hyphens) must be used to separate the options of reboot from the arguments of boot(1M).
example# reboot -dl -- -rv
Example 2: Rebooting Using a Specific Disk and Kernel
The following example reboots using a specific disk and kernel.
example# reboot disk1 kernel.test/unix
/var/adm/wtmpx login accounting file

The reboot utility does not execute the scripts in /etc/rcnum.d or execute shutdown actions in inittab(4). To ensure a complete shutdown
of system services, use shutdown(1M) or init(1M) to reboot a Solaris system.
