When attempting an incremental backup, sarab can fail when it does not find the reference backup. This occurs because the code to identify the reference backup does not account for having periods in the path or filename (ie.: /mnt/backup/.archive). A patch was created on the Sarab page on Sourceforge (http://sourceforge.net/tracker/index.php?func=detail&aid=1381136&group_id=91804&atid=598443) that contains the fix in the attached patch file.
Created attachment 81068 [details, diff] patch to correctly identify reference archive
Thanks for the note. This looks like a good fix to have. I've changed the patch you attached to use sed rather than perl. Please check it over and then I'll commit it to CVS.
Created attachment 81117 [details, diff] 0.2.2-refname-calculation-gentoo.patch replaces perl call with sed
That looks great to me.
Committed to CVS, thanks for the bug report.
