Hi!
I'm currently trying to move from a "incremental rdiff-backup on same
filesystem" to "modern filesystem with snapshots". (Yes, I know, this isn't a
real backup - it's not offsite yadda yadda. This is protection against "Wife
deletes her thesis by accident", no against "House burns down". Against that,
there's also offsite backups - but that's not the topic here.)
I plan to do the following:
1. Restore full backup of oldest existing version from $backup to $new
2. Take a snapshot of $new
2. For each increment:
2.1. List all changed/added files using:
zgrep -e '1\( [NA0-9]\+\)\{3\}$'
$backup/rdiff-backup-data/file_statistics.$timestamp.data.gz
2.2. Feed that into rdiff-backup using --include-filelist-stdin and --exclude *
and --force as files might already exist. (Of course, some awk magic is needed
here)
2.3. Take a snapshot of $new
Do you think this is a feasible approach? If not, what would you suggest for an
"incremental restore"?
Cheers,
Kosta
