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)

strncpy
STRCPY(3) Linux Programmer's Manual STRCPY(3)NAME
strcpy, strncpy - copy a string
SYNOPSIS
#include <string.h>
char *strcpy(char *dest, const char *src);
char *strncpy(char *dest, const char *src, size_t n);
DESCRIPTION
The strcpy() function copies the string pointed to by src (including the terminating ` ' character) to the array pointed to by dest. The
strings may not overlap, and the destination string dest must be large enough to receive the copy.
The strncpy() function is similar, except that not more than n bytes of src are copied. Thus, if there is no null byte among the first n
bytes of src, the result will not be null-terminated.
In the case where the length of src is less than that of n, the remainder of dest will be padded with nulls.
RETURN VALUE
The strcpy() and strncpy() functions return a pointer to the destination string dest.
BUGS
If the destination string of a strcpy() is not large enough (that is, if the programmer was stupid/lazy, and failed to check the size
before copying) then anything might happen. Overflowing fixed length strings is a favourite cracker technique.
