Well, I think I must have more explanation on my script. The script's
usage is like this:
~# fs_backup
Lack of backup identity name
program usage: fs_backup [OPTIONS] $identity
OPTIONS:
-a|--append [t/x[L]:$path, append 1 dir or file to $identity
t/x: include/exclude list, as -T/-X of 'tar'
L:file, append a batch of dirs/files to $identity by LIST
-d|--delete $path, delete 1 dir or file from $identity
-t|--type $type, specify the backup type: full/diff/incr
-D|--delete-outdated [f/d], delete outdated files/empty-dirs when
restoring.
-o 'option=value'
-w|--wrap 'wrap of tar options'
-h|--help, print this help message
For example, I want to backup /var/www/html, with excluding /var/www/
html/syssite/home/cache, and name this backup as pages, I will do
this:
sh# fs_backup -a t:/var/www/html pages
sh# fs_backup -a x:/var/www/html/syssite/home/cache pages
# These t/x have the same meaning of tar's '-T/-X'
sh# fs_backup -t full pages
sh# fs_backup -t incr pages
These will update /var/fs_backup/.table, (/var/fs_backup is 'datadir',
you can configure it to anywhere you like by editing the configuration
file, /etc/new/fs_backup.config):
pages, full, 20070204-231749, pages/pages.full.20070204-231749
pages, incr, 20070205-101011, pages/pages.incr.20070205-101011
......
May be I want add something to 'pages':
sh# fs_backup -a t:/usr/local/apache2/htdocs pages
sh# fs_backup -t full pages
Once I want recovery from the backup, I will do this:
sh# fs_rstore pages
This fs_rstore is just a symlink to fs_backup. All the files from the
last full backup will be restored.
The actually thing the script done is like this:
2007-03-18 20:32:20 fs_backup DEBUG find /mnt/file/data/ -cnewer /var/
fs_backup/work/.ts ! -type d -print >>/tmp/fs_backup.work.incr.
1174221140.0.list
2007-03-18 20:32:20 fs_backup DEBUG find /mnt/file/work/ -cnewer /var/
fs_backup/work/.ts ! -type d -print >>/tmp/fs_backup.work.incr.
1174221140.0.list
2007-03-18 20:32:20 fs_backup DEBUG tar -czp -P -f /var/fs_backup/work/
work.incr.20070318-203220.tgz -T /tmp/fs_backup.work.incr.
1174221140.0.list .identity .dirs .files
.dirs .files is just a snapshot of the current directories, which can
be used to delete-outdated files when restoring. Here I used absolute
path by using tar's -P parameter. When fs_rstore, it will do this:
command = "tar -xpz -P -f %s.tgz -T %s" % (archive, self.t_files)
maybe I want add some parameters of tar, for example, --strip-path=X,
so I hope the fs_rstore can do this:
sh# fs_rstore pages --strip-path=X
rather than:
sh# fs_rstore pages -w '--strip-path=X'
What should I do?
Thank you.
