You're on the 'master' - the backup server. The -h is how you specify which
host you want to do a restore of.
I should have been more clear about what BackupPC_tarCreate gives you - it
outputs a tar stream, which you then need to pipe or redirect into a file.
So something like:
/usr/share/backuppc/bin/BackupPC_tarCreate -h hostname -n -1 -s /var/backup/
employees.sql > employees.tar
Then run 'tar tvf employees.tar' to see if you actually have the file(s)
you're looking for. 'tar xvf employees.tar' will unpack the tarfile. There's
probably GUI ways to do this, but there are so many of them and they change
so often I can't say what to do.
The point of this exercise is to make sure you can get your files out.
Verify that you actually have your files. After that point you can worry
about fancy things like restoring files into place.
Personally, I don't allow the backup server to restore files into place.
Makes me nervous to allow the backup server to clobber files on the client
side.
It's only a couple of commands to capture the tar stream on the server side,
send it across the wire with 'netcat', then capture it on the other side
with 'netcat' and pipe the result to tar and unpack the files.
Here's a bit of documentation I wrote up a while ago on restoring files
across the wire. This is good to know because restoring files in place may
not always work for one reason or another. there may be some formatting
brokenness since I copied it as plain text out of a wiki.
===
When restoring files from backuppc, it often happens that you want to
restore many files, and don't want to download them from the web interface,
due to limitations of bandwidth or file handling capability. For example,
some operating systems have limits on how big the files may be, and some
software may not operate on files larger than a certain size (4GB .zip
files, for example).
To bypass the user interface, use the BackupPC_tarCreate command on the
command line.
$ /usr/share/backuppc/bin/BackupPC_tarCreate --help
/usr/share/backuppc/bin/BackupPC_tarCreate version [unknown] calling
Getopt::Std::getopts (version 1.05 [paranoid]),
running under Perl version 5.8.8.
Usage: BackupPC_tarCreate [-OPTIONS [-MORE_OPTIONS]] [--] [PROGRAM_ARG1 ...]
The following single-character options are accepted:
With arguments: -e -h -n -p -r -s -b -w
Boolean (without arguments): -L -l -t
Options may be merged together. -- stops processing of options.
Space is not required between options and their arguments.
[Now continuing due to backward compatibility and excessive paranoia.
See ``perldoc Getopt::Std'' about $Getopt::Std::STANDARD_HELP_VERSION.]
usage: /usr/share/backuppc/bin/BackupPC_tarCreate [options]
files/directories...
Required options:
-h host host from which the tar archive is created
-n dumpNum dump number from which the tar archive is created
A negative number means relative to the end (eg -1
means the most recent dump, -2 2nd most recent etc).
-s shareNameshare name from which the tar archive is created
Other options:
-t print summary totals
-r pathRemove path prefix that will be replaced with pathAdd
-p pathAdd new path prefix
-b BLOCKS BLOCKS x 512 bytes per record (default 20; same as tar)
-w writeBufSz write buffer size (default 1048576 = 1MB)
-e charset charset for encoding file names (default: value of
$Conf{ClientCharset} when backup was done)
-l just print a file listing; don't generate an archive
-L just print a detailed file listing; don't generate an
archive
You will need to become the backuppc user on the backup server.
To find the backup number (dumpNum), look at the web interface or in
/var/lib/backuppc/pc/ and see the timestamps on the number
directories.
Some examples of usage
This will take the last backup (number -1), the '/' share thereof, and the
'/etc' subdirectory from that share, and redirect the resulting tar stream
into a file called /var/tmp/host_example_com-etc.tar
/usr/share/backuppc/bin/BackupPC_tarCreate -n -1 -h host.example.com -s / /etc
> /var/tmp/host_example_com-etc.tar
This example takes everything ('/') from the 'docs' share, and streams it to
netcat, where it is directed at 'server' (which hopefully has a
corresponding netcat process listening for the data).
/usr/share/backuppc/bin/BackupPC_tarCreate -n -1 -h host.example.com -s docs /
| nc server
On the 'server' side of the above example, a command like this would recieve
the data and dump it into the current director
Re: [BackupPC-users] BackupPC - restore not restoring file
The -h host is the hostname of the client that has been backed up as if there
are multiple backups of hosts with the same file it
needs to specify which one.
So for example say you want to pull back share of /etc from a host I suspect
you're looking to do something alone the lines of:
/usr/share/backuppc/bin/BackupPC_tarCreate -h clientserver25 -n -1 -s /etc / >
/tmp/etc.tar
So in this -h clientserver25 refers to the name of a client you've already
backed up that you wish to restore a tar file from
as you may have countless clients with the same files and share names.
-n -1 refers to the most recent backup copies of files be they incrementals or
otherwise. You don';t need to worry about
exact paths within the backups taken, Backuppc will figure that out for you,
all you need to do is tell it to grab files/folders from
either a specific numbered backup or (using a negative value) a copy taken
relative to the most recent.
-s is the share name as specified in that client's config. This is coming from
$Conf{TarShareName} = '/etc'; or equivalent for
the host you wish to restore from. The next forward slash means everything
within that share and then redirect to a file as default is stdout.
The documentation could probably use a few typical usage examples and man pages
for the command line tools
like this to save a bit digging around in archives of this list.
Hope that helps

Subject: [BackupPC-users] BackupPC - restore not restoring file
I really dont understand the usage of backuppc_createtar
"-h host host from which the tar archive is created"
but I want to create a restore from the master , not create a tar from a remote
host ...I am sorry, I really dont understand
besides the command used for the restore is really close to rsync
for backup :
/usr/bin/ssh -q -x -l backuppc alderaan /usr/bin/rsync --server --sender
--numeric-ids --perms --owner --group -D --links --hard-links --times
--block-size=2048 --recursive --ignore-times . /var/backup/
so for restore, it should be something similar
