Hi,
I've been using duplicity for a while to backup daily changing
directories of logs and results.
I have always done this in the dead of night and locked the processes
which would usually write to the parent directory being backed up for the
duration of the backup.
However there is now a requirement to add to (and potentially even
modify) this directory 24/7. I've done a few tests and running
duplicity on a directory whilst that directory is being written to
doesn't seem to fail.
My question is - is backing up a potentially change directory supported?
Does duplicity initially snapshot the directory structure - so it will
ignore any new files or directories created whilst it is running? How
does it handle files potentially being changed or deleted during the
backup - if at all?
It strikes me that adding files shouldn't really be a problem (they will
simply be ignored until the next incremental backup) - but deleting or
modifying files mid-backup may be difficult to handle.
Any advice welcome!
Thanks,
Phil.
