Filename collision during backup

http://www.unix.com – Hi, I am trying to backup all *.tar files from a legacy Linux to a portable harddrive. find . -name "*.tar" -exec cp {} /media/mypassport/backup \; I found that there are files with the same filenames and they were overwritten in the destination folder. They are coming from different directories. To avoid filename collision, could you advise me how to backup and preserve the directory structure? Thanks, C. H. (HowTos)

Hi All,

I have MythBuntu 12.04.1 and Linux 3.2.0-38.

Going to Applications>System>Mythbuntu Control Centre>Backup and Restore> Getting Started>Backup>Backup Now>Directory: offers the choice of BU destination.

I'm running eclipse on windows and would like to automatically backup my src direcories for all my projects. I installed cygwin and tried to make a simple backup script but I am having trouble properly specifying the destination filename.

I would like to do a backup where I recursively go through a dir structure and only get directories with files whose names matching a particular regexp.

Beginner/Intermediate shell; comfortable in the command line.

I have been looking for a solution to a backup problem. I need to compare Directory 1 to Directory 2 and copy all modified or new files/directories from Directory 1 to Directory 3. I need the directory and file structure to be mirrored on Directory 3. Another way of thinking about the logic is: Dir1 - Dir2 = Dir3.

I had allot of help with the below script, and its been a long time since i've done anything with shell scripts so I am having some trouble.

I am trying to zip the trace folder after it is copied and dated but i'm unsure of how to tell it to zip this new folder without knowing what it will be named.

The script works fine as it is now but when it goes to remove the oldest backup it takes fore

I'm trying to setup a backup script on Ubuntu. Every day I want to copy my local source directory to a backup directory on a remote server uniquely named with the date. (e.g., backup-jan1/, backup-jan2/, etc) It should store a mirror of the earliest state and use difference files to recreate the new backup points.

This is pretty simple with rsync.

There's a backup configuration option to remount and unmount the backup drive which "requires a separate drive/coda/nfs mount". Later on, there's field labelled "Backup Destination" which "should be a directory/NFS/Coda mount".

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.

When I use rsync to backup something to an usb stick (formatted with an ext4 filesystem), rsync seems to preserve only the owner and group of the files but changes everything for directories to root and changes all permissions for directorys to drwx------ (permissions of files are preserved).

The exact command I used was:

sudo rsync -a /home/myuser/mydir/ /media/usb/backup/

Why are the director
