Hello,
I'm trying to use the "program" BackupPC_tarCreate.
I have a test-host wich has been backuped 4 times incrementally, and one time
fully :
- 0 : Full
- 1 : Incr
- 2 : Incr
- 3 : Incr
- 4 : Incr
So, I want to use tarCreate to make an archive of this host in the folder named
"/home/testback". So, here's my command :
# su backuppc
$ /usr/share/backuppc/bin/BackupPC_tarCreate -t -h test-host -s * -n -1
/home/testback/test.tar (to start from the last backup)
I also used :
- $ /usr/share/backuppc/bin/BackupPC_tarCreate -t -h test-host -s * -n
0 /home/testback/test.tar (to test with a positive number...?)
- $ /usr/share/backuppc/bin/BackupPC_tarCreate -t -h test-host -s * -n
-1 (to see if it was the path I put making mess...)
The error message is still the same :
/usr/share/backuppc/bin/BackupPC_tarCreate: bad dump number ''
What this message stands for ? I didn't found any help on Google...
There are several things wrong with your command line. First the
shell will expand an unquoted * to the list of files in your current
directory so it would be unpredictable what the program actually sees
as the resulting command line. Use either \* or '*' to prevent shell
expansions of wildcards. BackupPC_tarCreate doesn't want the output
file name on the command line - it writes to stdout, so you should use
shell redirection (>/path/to/file or | program), which again will
happen before the program sees the command line. Also, you do need
to specify the files/directories to include - using . or / will work
for 'everything'. Try:
/usr/share/backuppc/bin/BackupPC_tarCreate -t -h test-host -s '*' -n
-1 / >/home/testback/test.tar
or for testing you can:
/usr/share/backuppc/bin/BackupPC_tarCreate -t -h test-host -s '*' -n
-1 / | tar -tvf -
(list the filenames as they go by)
Also, note that it may not make sense to wild-card the shares if they
weren't collected in the natural mounted tree locations (for example,
if you have windows shares of C$, E$, etc.)

I tried this command :
/usr/share/backuppc/bin/BackupPC_tarCreate -t -h test-host -s '*' -n
-1 / >/home/test-host.tar
It works perfectly. ;)
In fact, I want to make what BackupPC GUI does (Start archive>Select all
(in my case)>Archive selected hosts). I read that it must be done by an
executable script with cron.
So, your command makes a tar, then I must compress it with bzip2. Is
there a way to compress it "on the fly" ?
I ran the last command and I put "| bzip2 -v myfile.tar", at the end of
the command, but it doesn't work, it makes me a file sizes 14o...
So, is there a way to make what BackupPC GUI does, automatically ? Cron
job or anything else ?
Thanks :)
