Backup - how do you manage it..?
With heaps of photos in my library - many thousands - I make sure I do regular backups. Hard disks do fail so backup is important. Here is how I manage it. I use an iMac so I have access to Apples Time Machine, which is very good as a way of letting the software take control and manage the backup for me.
However, I have seen several corrupted Time Machine backups (it has not happened to me though) which has made me cautious enough to use a secondary backup system.
I have an old Linux box connected to my very small home network that I copy all files across to on a regular basis. Sounds like a real chore but it is not. Using Terminal and the command line utility rsync I manage to copy all new files in a few seconds. The first time this is done it will take some time if you have a large store of files, but all subsequent copies are quick: it does not copy files that have not changed.
Here is what I do: this assumes that all my pictures are stored on an external LaCie disk with the pictures in a folder called Pictures off the root of the LaCie drive.
>rsync -avz Pictures/ firstname.lastname@example.org:/share/photo-backup
Login to this system as the admin user and all the files from Pictures will start to copy across.
>rsync Pictures/ : A trailing slash on the source changes this behaviour to avoid creating an additional directory level at the destination. You can think of a trailing / on a source as meaning "copy the contents of this directory" as opposed to "copy the directory by name", but in both cases the attributes of the containing directory are transferred to the containing directory on the destination.
>rsync -avz Pictures/ : the parameters -avz refer to the following:
-a = means the copy in archive mode - it preserves everything
-v = verbose mode - information is given about the transfer process
-z = compress the files before transferring, really useful over a slow connection but probably not important in a small network connection.
