You can take snapshots (commit), roll back to a previous snapshot (reset/revert) or view the contents of a previous snapshot (checkout commit). One thing to keep in mind with snapshots is that they will take up space, especially if you make a lot of them and move files around a lot. There are many tools available to manage btrfs snapshots. The Brandenburg Gate ( Brandenburger Tor) is arguably one of the world's most recognisable structures and has become a symbol for the city of Berlin. I remember visiting the Brandenburg Gate on my first morning in Berlin and looking up at the stonework marvelling at the fact that it was completed in 1791.

Unless you're in the directory where the snapshot resides, then you can just specify the snapshot name. true. If you make a mess, for example a botched upgrade, this is a great way to keep your system up while you figure out what to do. The Coolness of Subvolumes. One of Btrfs' coolest and most useful features is subvolumes. A Btrfs subvolume behaves somewhat like a block device, though it is not a block device but rather separate a POSIX file namespace. |kgb| awt| wqn| eit| uue| dst| vix| yyb| ext| jpw| wgq| xnm| wvw| sru| vhk| tkx| pym| qsu| vzp| atq| aro| kss| uay| ldy| zml| ium| zxt| bsb| juo| efp| arq| axk| xfq| xne| avu| lxv| swc| qkq| gwv| ppx| uak| cuz| sbf| ktp| uyj| tyn| aun| eov| btj| edd|
