[flexbackup-help] timestamp files and ctime

[Karl-Michael S. <sch...@ph...>]

Hello,

I started using flexbackup, nice tool.

The changes for version 0.9.9.7 (200301015) talk about considering ctime when
selecting files for backup. This currently only works for local backups, not
remote backups. Are there any plans to make ctime checking available also for
remote backups? This could possibly be done by storing timestamp files for
remote backups on the remote machine rather than on the local machine.

Another problem with ctime is that even for local backups, the timestamp file
is created after the backup has finished. Its mtime is set to the beginning of
the backup, but its ctime is obviously set to the time the file is created,
i.e. after the backup, so files whose attributes changed during the backup will
not be considered in the next backup. Timestamp files should be created at the
beginnning of the backup.

I made some changes to the flexbackup perl script that implement the following:

- timestamp files for backups from remote hosts are kept on the remote hosts.
  This solves the problem that ctime could not be considered on remote files.

- timestamp files are created at the start of the backup rather than at the
  end. When timestamp files are created at the end of the backup, files that
  change or are created while the backup is in progress will not be considered
  for subsequent backups with higher backup level.

I'm running this version on my system and it works fine. Is there a place where
I can submit the changes?
