Top Forums Shell Programming and Scripting How to copy very large directory trees Post 302730001 by Chubler_XL on Monday 12th of November 2012 04:56:14 AM

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

Code:
rsync -avc --del --partial /path/to/source/files/ dest:/path/to/dest/files

also consider something like --bwlimit=4000 to avoid swamping your network by limiting the transfer to 4Mbps.

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. CONFORMING TO
