[flexbackup-help] Newbie help please?

[s. k. <ke...@sp...>]

What an ordeal.  :-P

First, thanks for flexbackup.  I think it's just what I'm looking
for.  Once I have it actually working, it should be quite a nice tool.

I've installed it on one of my servers (running Debian
testing/Sarge).  I created a user account which can do passwordless
ssh logins to the server I'm trying to backup (Fedora Core 1 -
Blecchh!).  I spent some time trying to figure out how to get afio on
FC1 and finally gave up and went with tar instead.  I'm backing up to
disk, not tape.

To test it out, I ran (as root):

  flexbackup -set servhm

where "servhm" is defined as "f.q.d.n:/home" in /etc/flexbackup.conf.
That whipped along for quite a while, then complained:

tar: ./bbuser/.bash_history: Warning: Cannot open: Permission denied
tar: ./bbuser/.ssh: Warning: Cannot savedir: Permission denied

then:

Total bytes written: 886599680 (845MB, 694kB/s)
0+69304 records in
27721+1 records out
283866703 bytes transferred in 1254.644564 seconds (226253 bytes/sec)

     exit ${x[$i]}; i=$(($i+1)); done' | dd ibs=10k obs=10k
     conv=noerror \
     of="/var/flexb/archive/f.q.d.n-home.0.tar.bz2"

ERROR: exiting


Why did it complain about bbuser and not the other users' files?  The
permissions on his home dir are the same as everyone else's and the
perms on those files are correct.

Why did it go through all that then blow away the archive it was
creating?  The index is still there, but no backup.

Why does the flexbackup command prompt me for the flexbackup user's
password?  How am I supposed to stuff this into a cron job when that's
going on?

I'm making the flexbackup user do the remote stuff via sudo.  What do
I need to allow in /etc/sudoers for flexbackup to work?

Thanks for any help you can offer.

[flexbackup-help] pkgdelta for slackware

[Lukasz S. <admin-flexbackup@k.telmark.waw.pl>]

Greetings all.

Here you are a script to get list of "stock" files for Slackware.
sed -e '1,/^FILE LIST:/d' \
 -e '/^install/d' \
 -e '/^etc/d' \
 -e '/\/$/d' /var/log/packages/*

Let me descreibe each expression.
#1 Jump a package description
#2 The "install" directory is always removed by pkginstall just
   after the inslation so it doesn't mean anythig.
#3 Skip configuration files, we always need them on the tape.
#4 Skip directories, all descriptions are kept in the /var/log/packages

[flexbackup-help] Date format

[Breeijen, W.M. d. \(CTW\) <W.M...@ct...>]

Does anybody know how to change the format of the date-part in the
backup and log files?

Now I get files like users.0.200502081010.gz and
storage-usr-people.0.200502081010.tar.gz,
but I prefer something like users.0.2005.02.08-10.10.gz and
storage-usr-people.0.2005.02.08-10.10.tar.gz
Which is much more human readable. There's no option in flexbackup.conf
I think.

Is it safe to just modify line 3690 from=20
   $string =3D strftime("%Y%m%d%H%M", localtime($current_time));
to
   $string =3D strftime("%Y.%m.%d-%H.%M", localtime($current_time));

Thanks in advance,
Wouter.

 Hello all,

I encountered the same problem.
Hope the following patch to flexbackup script solve your problem.
Not widely tested, maybe the bad way to do it, but it works on freebsd
flexbackup server with freebsd (using freebsd find) and solaris clients 
(using

So it will works probably in your environnement.

Don't use dump for that filesystem (or any other network file system).

What I do is to mount (smbmount) the directory and then use fb.

some kind of

smbmount //aguasanta/SandboxesPFP /mnt/aguasanta/PFP -o 
credentials=/root/.credentials
if [ "$?" -eq $SUCCESS ]
   then
           flexbackup -set Aguasanta.PFP -full

You can't dump an smb file system (or maybe any remote file system). Try 
tar. Or star. Or do the backup on the system where the file system

[flexbackup-help] dumping a samba directory

[RYAN v. G. <mai...@co...>]

does anyone know how to dump a samba directory i keep getting this error

[flexbackup-help] Flexbackup with star...

[medspx <me...@te...>]

Hello,

I tried yesterday to implement a backup system on my new Debian Sarge 
server (so the flexbackup version is the Debian testing packet 1.2.1). I 
have to save ACL of my samba shares so, I have chosen to use flexbackup 
and star to make the job: a backup on an SDLT SCSI tape.

The backup operation was quite good so I decided to go further with a 
restoration test.
Then , I've faced two problems (perhaps bugs):
- ACL wasn't restored at all.
- Every GID/UID of directories where root/root (made the restoration 
with root account).

For the first problem, I've found that if the star acl support is 
implemented in flexbackup script, it's not implemented in the 
restoration part. So I had to add two lines in the script:

######################################################################
# Extract files (maybe a list) to current directory
######################################################################
sub extract_routine {

...

} elsif ($cfg::type eq 'star') {
	$cmd .= "$::path{star} -x ";
	if ($restore_files ne '') {
	    $cmd .= "list=$newlist ";
	}
	$cmd .= "-p ";
	$cmd .= "$::star_fifo_flag ";
	$cmd .= "$::star_verb_flag ";
	$cmd .= "$::star_sparse_flag ";
	$cmd .= "H=$cfg::star_format "; <<----------------- This one was added
	$cmd .= "$::star_acl_flag "; <<-----------------This one was added
        $cmd .= "$::star_blocknum_flag ";
	$cmd .= "$::star_blk_flag ";
	$cmd .= "-B ";
	$cmd .= "file=-";

...
And it works OK ! I think that somebody forgot something for the 
extraction with star.

But my second problem wasn't solved by adding those lines. After a few 
tests and checks, I managed to understand that the bug comes from the 
way the archive is build up on backup. I believe that passing a list of 
files and directories directly to star (by the command find in a pipe) 
is responsible of my problem.
So, I've changed the code in the backup part in order to make star build 
it's own list of files to backup (just a * in the command line).
Here are my changes:

######################################################################
# Return command to backup a directory using star
######################################################################
sub backup_star {

    my $label = shift(@_);
    my $dir = shift(@_);
    my $title = shift(@_);
    my $level = shift(@_);
    my $remote = shift(@_);
    my $cmd = '';
    my @cmds;
    my $stamp = "$cfg::tmpdir/refdate.$PROCESS_ID";
    my $remove = '';

    if (defined($remote) and ($level != 0)) {
	my $time = &get_last_date($label, $level, 'numeric');
	$cmd = "$::path{touch} -t \"$time\" $stamp";
	push(@cmds, &maybe_remote_cmd($cmd, $remote));
	$remove .= " $stamp";
    } else {
	$stamp = &get_last_date($label, $level, 'filename');
    }

    $cmd = "cd \"$dir\" && ";
#    $cmd .= &file_list_cmd($dir, $stamp, 'newline', $level, $remote); <<---- We do not want to use find
#    $cmd .= "| "; <<--- So this pipe is not used

    $cmd .= "$::path{star} -c ";
#    $cmd .= "list=- "; <<--- star command line manipulation
    $cmd .= "-p ";
    $cmd .= "-l ";
#    $cmd .= "-D "; <<---- We want to descend in the directories so no -D option
    $cmd .= "-B ";
#    $cmd .= "-dirmode "; <<--- same for dirmode
    if ($cfg::label ne 'false') {
	$cmd .= "VOLHDR=\"$title\" ";
    }
    $cmd .= "H=$cfg::star_format ";
    $cmd .= "$::star_fifo_flag ";
    $cmd .= "$::star_acl_flag ";
    $cmd .= "$::star_verb_flag ";
    $cmd .= "$::star_sparse_flag ";
    $cmd .= "$::star_atime_flag ";
    $cmd .= "$::star_blocknum_flag ";
    $cmd .= "$::star_blk_flag ";
    $cmd .= "file=- ";
    $cmd .= "* $::z"; <<---------- We simply add a joker * in order to go through the set (flexbackup set).
...


With those changes in the script,all my backup/restore tests succeded...
I hope this message helps people solving their problem of flexbackup use with star.
But perhaps haven't you got the same problems and it is only a misconfiguration of something else ? Who knows ?

[flexbackup-help] flexbackup and mbuffer

[John H. B. I. <ben...@th...>]

Hello,
 
Has anyone done much testing with flexbackup using mbuffer and restoring
from spanned tapes?  It seems you can span tapes for the backup just fine,
but people are having problems restoring files from the spanned tape.  I am
just curious, as I have been using flexbackup for quite a while, but am
needing a solution that I can use to backup and restore data from multiple
volume backups.
 
Thanks,

[flexbackup-help] flexbackup 1.2.1 on Solaris 8

[Adam R. <aro...@ci...>]

Hi All -

Just thought I'd share what I needed to do to get v1.2.1 to run properly on
Solaris.

On line 849 of the flexbackup script, there is the following line:

	push(@cmds, "[ ! -e $result ]");


The "-e" test is not applicable to the standard Bourne shell, which would
ultimately cause the script to error out with the following message:

sh: test: argument expected


Changing the line to read:

	push(@cmds, "[ ! -f $result ]");


results in a working script.

-Adam

Prune is per file systems, so use this :

[flexbackup-help] prune problems

[Pierluigi Di L. <li...@ep...>]

I'm a flexbackup user from about 4 months.
I'm having problem using $prune option to exclude some directory.
I'm backing up /home ($set{'backup'} = "/home";) using dump and I want to
exclude subdirectory /home/backup and /home/images/mondo
I tried with variuos combinations like:
$prune{'/'} = "backup images/mondo";
and others, with the same result of not excluding files from backup.
I read faq, perhaps I don't understand how regex works :(
Can someone explain how can I do this?
Thank's in advance!

[flexbackup-help] backuping remote FreeBSD from Linux computer problem

[Evgeniy Z. <ei...@ro...>]

Hello flexbackup-help,

I use Flexbackup 1.2.1 for backup data by the machines scattered in a network.
Flexbackup it is started under user 'backup' and for backuping data on remote machines it is used
ssh-keys without password and with sudo-command.

On the majority of machines as operational system stand Linux (Gentoo). The data normally backuping.

But I have faced a problem at attempt to backup data on remote FreeBSD machine 
(start flexbackup occurs by the linux-machine):

Flexbackup 1.2.1
Gentoo Linux ======= ssh =====> FreeBSD 5.3

The problem consists that $prune={"} directories are not ignored as the linux-machine
transfers on the bsd-machine the next line (for example):

ssh -l bbb remote-bsd 'cd "/home" && sudo find . -regex "\./\(ftp\|mysql\|backup/data\)/.*" -prune -o
(using csh-shell,
$prune={'remote-bsd:/home'} = "ftp mysql backup/data";
)
this list of directories are not prune from backup-list on
FreeBSD-mashine.

For FreeBSD it is necessary to specify in addition a key "-E" for find-utility and to NOT escape ("\|","\)"...) symbols "|", ")" and "(".
Problem in that Flexbackup check of operational system goes only at start, i.e. by the local machine.
And that fact, that a command will be executed on other OS, it is not taken
(if  start flexbackup with the same options directly on freebsd-mashine, all parameters, including "-E" are transferred the utility find correctly).


Unfortunately, my knowledge does not suffice for correction of this problem. 
Someone can it already has solved?

Re: [flexbackup-help] Flexbackup extract problem

[Markus B. <bl...@SC...>]

Thank you for your quick answer.
I also tried it without '.z' at the end, but it comes up with an error,
can't remember it exactly
And it also says in the FAQ:

    To quickly extract just a single file, use "-extract -onefile
path/to/my/file", giving the path from the archive.

    To extract a list of multiple files, put them into a text file, for
instance "restorelist", then use "-extract -flist 	restorelist". The
format is one line per pathname, using the path of the file in the =
archive.
Note if you are using 	afio with compression you need to append ".z" to
filenames for any compressed files (depends on threshold and exclusion
patterns).

But anyway why does it say "succesful"?

You can try to do
flexbackup -extract -num 1 -onefile 
CategorieManagementEinkauf/Kunden/Hersteller/Software/Konsi/tewi/Masterlisten/Masterliste_Tewi_aktuell.xls 


without z at to the end.

[flexbackup-help] Flexbackup extract problem

[Markus B. <bl...@SC...>]

Hello all,

I have a problem, I can't extract a file that is on my Backup-Tape
I know, that it is on my tape, as it shows up, when doing a 


[root@SV250L01 Abteilung]# flexbackup -num 1 -list > list.txt &
[root@SV250L01 Abteilung]# grep Masterliste_Tewi_aktuell list.txt
-rwxrwxr-x  1 stagliaferro Benutzer   495210 Dec  2 11:10:42 2004
CategorieManagementEinkauf/Kunden/Hersteller/Software/Konsi/tewi/Masterliste
n/Masterliste_Tewi_aktuell.xls -- compressed
[root@SV250L01 Abteilung]#

When trying to extract that file, I do the following:


[root@SV250L01 Abteilung]# pwd
/daten2/Abteilung
[root@SV250L01 Abteilung]# flexbackup -extract -num 1 -onefile
CategorieManagementEinkauf/Kunden/Hersteller/Software/Konsi/te
 wi/Masterlisten/Masterliste_Tewi_aktuell.xls.z 


The output says, that everything was ok and that the file should be
extracted, but i can'T find it afterwards :

[flexbackup-help] Extract problem

[Darrick H. <dha...@dj...>]

Reading the FAQ AFTER the fact looks like I may have a serious problem.

I backed up a directory using flexbackup with tar and bzip2 compression. 
  I'm using flexbackup 1.2.1 with mbuffer.

During the backup, flexbackup prompted me for a second tape.  I put in 
the second tape and pressed enter (as prompted) to continue.

Now I am unable to extract the data from the second tape.  I'm not 
concerned about the file at the transition point, but I need the 
remaining data after that point.

Below is a list of the commands I used, and the results.

I appreciate any help.  Going forward, it looks like one tape is the 
best way to go.

Thanks,

Darrick

bzip2: Compressed file ends unexpectedly;
         perhaps it is corrupted?  *Possible* reason follows.
bzip2: Invalid argument
         Input file = (stdin), output file = (stdout)

It is possible that the compressed file(s) have become corrupted.
You can use the -tvv option to test integrity of such files.

You can use the `bzip2recover' program to attempt to recover
data from undamaged sections of corrupted files.

[flexbackup-help] problem...

[Dawid C. <qb...@f-...>]

Helo.
I have a problem while making backup  with flexbackup.
I have

$set{'bkp-all'} = "/";
$prune{'/'} = "tmp proc backup var/spool/squid home/users"

When i do  
flexbackup -set bkp-all -full 
some things really do backup, but i see in log that the whole 'home' is
not even mentioned in log. 'bin' 'usr' 'root' are present but without
their contents.

What is wrong ? What do i wrong ?

Thanks for any help.

[flexbackup-help] owner of file

[Michele C. <mi...@pr...>]

Hi,
I'm using flexbackup 1.2.1 from few days, with afio and gzip to compress 
file.
Everythings is Ok if I use flexbackup with root permission, but I need 
to use it with nobody permission.
I created a file wrapper to have root permission and put to 4755 
permission to afio,tee,touch commands.
Now I can backup with user nobody any files with root permission. The 
only problem I have is in the extract operation.
With user nobody I can extract files, but the owner of these files is 
always nobody, and not the original user.

Can someone help me?
Michele

[flexbackup-help] Time Stamp files

[Mick E. <Mic...@ub...>]

Hi Scot,

Yes that's the problem. The timestamp files aren't being created. The
directory exists and I am running as root so it shouldn't be a
permissions problem. I have the following in my config:

$stampdir = '/var/lib/flexbackup'; # directory for backup timestamps

and dumpdates is set to false:

# True to use /etc/dumpdates (could mess things up if you dump
subdirectories
# of mount points).  False to use flexbackup's timestamps.
$dump_use_dumpdates = 'false';

I am using tar to create the backups. I am not getting any errors when
the full backup is created.

Regards,
Mick.

Time stamps are files placed in the '$stampdir' directory (which is set
to '/var/lib/flexbackup' in the default /etc/flexbackup.conf file).

Are there any files in that directory?

[flexbackup-help] timestamp not found

[Mick E. <Mic...@ub...>]

Hi all,

While attempting to do a level 1 backup following a level 0 I get the
following error:

Can't do a level 1 backup - no level 0 timestamp found
at /usr/bin/flexbackup line 2288

I have checked the list archive and read the posts at
http://sourceforge.net/mailarchive/forum.php?thread_id=5191099&forum_id=21263

I have been unable to find an explanation of this error either here or
elswhere. If anyone can shed any light on this I would greatly
appreciate it.

Regards,
Mick.
