  • Maintaining a Dead Project: Do I Fork?

    I've been trying to contact the developers of the SourceForge-hosted flexbackup project off and on for about a year with no response. The last update was in 2003 and none of the listed developers have responded to emails even once. Two questions, then: 1) Is there a policy whereby a new developer can be added after some sort of statute of limitations has expired? I suspect not. 2) If...

  • Comment: Flexbackup not correctly excluding directories.

    Exclude is really designed for individual files that may occur anywhere, not for specific paths where you want to exclude all files under that path. Use prune instead. For your example, if your backup set was baching up from the root of the volume (i.e., "/"), then the prune term would be: $prune{'/'} = 'ftp/anonymous/media'; Note that, with prune and exclude that the terms are...

  • flexbackup subtle subtree pruning issue

    When you specify a list of directories to prune, flexbackup gets it almost right. It backs up all of the directories on the pruning list but none of the contents of those directories. As such, little space is wasted in the backup and it's more if a nit than a real show stopper. The issue was that flexbackup was taking the list of directories, for instance, like this one...

  • flexbackup specifies wrong command line option for mbuffer

    Flexbackup uses either the buffer or mbuffer program to help streaming tape drives from thrashing. The buffer program uses the -p command line option to specify the percentage the buffer to fill before writing data. Alas, mbuffer's command line is insidiously incompatible with buffer in this: it uses -P (capital P) instead of -p (lowercase p) to mean the same thing. In mbuffer -p (lowercase p)
