Re: [PLUG] non-nerdy ... a non-rant
|
I just use 'cp' to copy files from the source disk to an external USB
disk, copying on a partition by partition basis. The backup disk
partitioning matches the source. Size of the destination partitions does
not matter as long as they are at least as large as the source.
One drawback is that files that have been deleted (and backed up on a
prior backup) remain on the backup. I get around this by using two backup
drives and occasionally deleting all files on the backup and starting
fresh. This backup script only backs up files that have changed.
Although I have never had to do it the backup drive should be replacable
to the main drive for booting shold that be necessary.
