I also had data loss with ext4. The "feature" responsible for this is delayed allocation. With delayed allocation on all hd-writes are held back in memory, so if you just cut the power the data is lost.
Basically the old version should be still available, but perhaps ext4 decides that a zeroed file is more "consistent". -- Ext4 data loss https://bugs.launchpad.net/bugs/317781 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
