Could anyone please let me know the meaning of "writeback"?

As in "plan writeback".

It's related to IT project planning.

Thanx in advance.

WBWA: Both the L1 cache and victim cache have dirty bits. Blocks are managed exactly as described above (see victim cache description), only make sure to carry dirty bits with blocks wherever they go. Definition of 鈥渨riteback鈥? In a system without a victim cache, replacing a dirty block in the L1 cache causes a writeback to memory, and it is counted towards the 鈥渨riteback鈥?statistic. However, if there is a victim cache, the replaced block and its dirty bit are sent to the victim cache, and we do not call this a 鈥渨riteback鈥?because it isn鈥檛 sent to memory. When a LRU dirty block is replaced in the victim cache (not swapped!), it is written back to
memory and counts toward the 鈥渨riteback鈥?statistic. In summary, in a system with a victim cache, writebacks can only occur from the victim cache; in a system without a victim cache, writebacks occur from the L1 cache.

Writeback, where metadata is journaled but file contents are not. This is faster, but introduces the hazard of out-of-order writes where, for example, files being appended to during a crash may gain a tail of garbage on the next mount.
