增量备份和差异备份的区别

1. 增量备份：
增量备份只保留上次完整备份或增量备份后发生变化的数据。这种类型的备份使用较少的存储，并且可以快速进行备份和恢复。此类备份中的数据包含冗余，因为恢复包括上次完整备份和所有增量备份。

2. 差异备份：
差异备份仅保留上次完整备份的数据更改。这种类型的备份使用更多内存，因为它保存自上次完整备份以来的所有数据更改。它包含的冗余数据较少，恢复很容易，但创建备份所需的时间很长。

增量备份和差异备份的区别：

S.NO.	Incremental Backup	Differential Backup
1.	In this type of backup successive copies of data contains only the changed part since the preceding backup copy was made.	In this type of backup only the difference in the data from last full backup is saved.
2.	It has more redundant data than differential backup.	Differential backup contains less redundant data.
3.	Recovery is difficult in this type of backup.	Recovery is easy as compared to incremental backup.
4.	It takes less time to create backup.	It takes more time to create backup than incremental backup.
5.	It take less data storage space to create backup.	Memory taken to create backup is more as compared to incremental backup.
6.	Incremental backup uses less bandwidth.	Differential backup uses more bandwidth than incremental backup.
