Let us start with simple example where we mirror local directory to remote directory.
This configuration will backup/mirror our pictures from user home folder ~/Pictures (use something like c:\Users\me\Pictures on Windows)
to other local folder (for example mounted NAS in /mnt/nas).
1 storage.filesystem.basedir=~/Pictures
2 storage.target.basedir=/mnt/nas
3 storage.target.class = Storage_Filesystem
4 compare.sqlite.file=~/xtbackup.db
5
6 engine.outputs[]=cli
7 engine.local=filesystem
8 engine.remote=target
9 engine.compare=sqlite
line 1: We configure source for data. Data are handled by storage driver, so the first key is storage. Second key is name of
the storage configuration. It could be any name, but because we have chosen same name as name of driver (filesystem) we don't need to specify
drivers class, it will be deducted by xtbackup.
line 2: We configure target for data. Again, it is about data, it will be handled by storage driver, so it is defined under storage key.
We name this storage configuration as target.
line 3: We have to manually specify driver class, because the driver class to be used with target configuration will not be automaticaly deducted by xtbackup.
line 4: Except storage drivers we have to configure compare driver. Minimal configuration requires where sqlite database file should be stored. This location shouldn't be on temporary device,
Next lines configure engine driver and bind everything together.
line 7: the key local maps storage configuration key which will be used as data source
line 8: the key remote maps storage configuration key which will be used as data target
line 9: the key compare maps compare configuration key
