Dejavu is a Java library that allows you to create in-memory snapshots of the internal status of your objects at different points of time and to restore that status later. It is inspired by the Memento design pattern, and allows you to easily implement undo-redo, rollback, etc.

bup-restore - extract files from a backup set
SYNOPSIS
bup restore [--outdir=outdir] [-v] [-q]
DESCRIPTION
bup restore extracts files from a backup set (created with bup-save(1)) to the local filesystem.
The specified paths are of the form /branch/revision/path/to/file. The components of the path are as follows:
branch the name of the backup set to restore from; this corresponds to the --name (-n) option to bup save.
revision
the revision of the backup set to restore. The revision latest is always the most recent backup on the given branch. You can dis-
cover other revisions using bup ls /branch.
/path/to/file
the original absolute filesystem path to the file you want to restore. For example, /etc/passwd.
Note: if the /path/to/file is a directory, bup restore will restore that directory as well as recursively restoring all its contents.
If /path/to/file is a directory ending in a slash (ie. /path/to/dir/), bup restore will restore the children of that directory directly to
the current directory (or the --outdir). If the directory does not end in a slash, the children will be restored to a subdirectory of the
current directory. See the EXAMPLES section to see how this works.
OPTIONS -C, --outdir=outdir
create and change to directory outdir before extracting the files.
-v, --verbose
increase log output. Given once, prints every directory as it is restored; given twice, prints every file and directory.
-q, --quiet
don't show the progress meter. Normally, is stderr is a tty, a progress display is printed that shows the total number of files
restored.
EXAMPLE
Create a simple test backup set:
$ bup index -u /etc
$ bup save -n mybackup /etc/passwd /etc/profile
Restore just one file:
$ bup restore /mybackup/latest/etc/passwd
Restoring: 1, done.
$ ls -l passwd
-rw-r--r-- 1 apenwarr apenwarr 1478 2010-09-08 03:06 passwd
Restore the whole directory (no trailing slash):
$ bup restore -C test1 /mybackup/latest/etc
Restoring: 3, done.
$ find test1
test1
test1/etc
test1/etc/passwd
test1/etc/profile
Restore the whole directory (trailing slash):
$ bup restore -C test2 /mybackup/latest/etc/
Restoring: 2, done.
$ find test2
test2
test2/passwd
test2/profile
