I defined two parameters: Volume name = volname and Count = 1. My understanding was that once the number of restored files hit the Count value bextract would stop. This wasn't the case. I also used an include-list file when running bextract so there may be a clash when using -b and -i command-line options. I wasn't able to provide all the parameters to use just a bootstrap file. Details are: bextract -b bootstrap-file -i include-list -V TAPE_04 /dev/nst0 /mnt/restores include-list file contents: /Backups/VM09_Full_backup.vbk bootstrap-file file contents: Volume = TAPE_04 Count = 1 In the end I used the interrupt approach -- once the first file was restored I interrupted the bextract process before it got to the second occurrence of the file. Ironically this is the only tape in the entire monthly backup set that includes the same file twice! cby -- View this message in context: http://www.nabble.com/bextractrestore-single-occurrence-of-file-tp25905115p25937562.html Sent from the Bacula - Users mailing list archive at Nabble.com. -- Come build with us!

I suggest you open a bug-report/feature request on this.. this seems like a really nasty situation to get into if stuff really "burns". Jesper -- Come build with us!

[Bacula-users] bextract -- restore single occurrence of file
Hi Running bacula on Centos 5.2 I have a tape volume which has more than one occurrence of the same filename as a result of appending to tape. I needed to restore the first file. I fired up bextract (standard bacula restore is not appropriate in this case) which restored the first occurrence of the file as expected. However, instead of halting after restoring the file, bextract continued to the end of the tape and found a second occurrence with the same filename which it duly restored replacing the originally restored file. Bearing in mind that the file is over 300GB (Veeam backup) I want to avoid a repeat of this exercise without being able to halt bextract after the initial file restore. I have looked through the bacula documentation and usual places but there does not appear to be an obvious way to instruct bextract to restore the first occurrence of a file. Fortunately the two files were written some distance apart on the tape so I can kill the bextract process once the first file has been restored. Not exactly elegant but it should work. I'd be grateful for any suggestions in how bextract itself can achieve this without recourse to my sledgehammer approach! Thanks. -- View this message in context: http://www.nabble.com/bextractrestore-single-occurrence-of-file-tp25905115p25905115.html Sent from the Bacula - Users mailing list archive at Nabble.com. -- Come build with us!
