Traditional Unix file systems required a lengthy, disruptive check ( fsck ) after an unexpected power failure. Systems like IBM AIX and Veritas File System (VxFS) utilized journaling. By writing metadata changes to a dedicated log before applying them, a system could recover from a crash in seconds rather than hours.
