(pseudo) incremental backup with different exclude lists using hardlinks and rsync
e917546ad1
But this is definitly the WRONG way.
We cannot, we need not and we MUST NOT try to catch dumb users.
Instead we are the program, we may give the rules. And if we add a fancy
feature and the user is too dumb to use it, it is HER/HIS fault.
Just to remind my self:
Add use of other backup intervals as source for this interval
with the following behaviour:
- locate all possible intervals in
* default configuration
* source specific configuration
- locate all backups for each interval, record only the timestamp:
* taeglich.2007-01-23-0042
-> possible_old_sources += taeglich
-> taeglich_last=2007-01-23-0042
- NO READ NEED for this! other method:
* sort by time, ALL possible backup:
- does posix-ls support this? CHECK!
- ( cd $C_SOURCE/destination/;
ls --sort-by-time "$interval1".* "$interval2".* |
tail -n1 )
- catches all possible intervals
- add optional behaviour:
* prefer other interval (newer) over this one

-------------------------------------------------------------------------------- ccollect.sh, Nico Schottelius, 2005-12-06 -------------------------------------------------------------------------------- ccollect backups data from local or remote hosts to your local harddisk. You can retriev the latest version of ccollect at [0]. ccollect was inspired by rsnapshot [1], which has some problems: - configuration parameters has to be TAB seperated - you can not specify per source exclude lists - no per source pre/post execution support - no parallel execution - does unecessary moving of backup directories - I didn't like the configuration at all, so I used the cconfig style [2].
