Migrating from ext4/linked files to btrfs



From one of the amazon server, which was using symlink/hardlink mode
A few month ago, we migrated the storage to a brtrfs storage using urbackup built-in tool
However at this point /etc/urbackup/backupfolder was not set

Now i created /etc/urbackup/backupfolder with the same target that the one set for the data folder in the web-ui
urbackup_snapshot_helper test is sucessfull
I can browse older backups which were done in link mode and newer backup in btrfs special mode

Did i just break everything in a very subtle way, or everything is now working perfectly ?
(i thought it was not possible to switch and a fresh installation was required)
Either way, could the migration path for older users like me be documented ?


No, should work. It can switch back and forth to snapshot mode wo. issues.
