我正在尝试使用 (dump) restore -command 从增量备份中恢复 linux ext4 文件系统。我使用 hanoi 塔策略进行备份,转储如下所示,按时间排序:
root@server:/backup# ls -alth
-rw-r--r-- 1 backup backup 264305457 Oct 2 22:05 l2-phz-xvda2-001
-rw-r--r-- 1 backup backup 755017563 Nov 3 22:13 l1-phz-xvda2-001
-rw-r--r-- 1 backup backup 1734399 Nov 11 22:00 l4-phz-xvda2-001
-rw-r--r-- 1 backup backup 498703367 Nov 19 22:08 l3-phz-xvda2-001
-rw-r--r-- 1 backup backup 2304401315 Jan 1 22:47 l0-phz-xvda2-001
-rw-r--r-- 1 backup backup 933481 Jan 5 22:00 l5-phz-xvda2-001
-rw-r--r-- 1 backup backup 122383278 Jan 6 22:02 l7-phz-xvda2-001
-rw-r--r-- 1 backup backup 122803554 Jan 7 22:02 l6-phz-xvda2-001
由于 0 级转储是完整转储,我首先恢复了它,但是当我尝试恢复下一个(l5)转储时,收到以下错误消息:
restore -rMf /backup/l5-phz-xvda2- -b 256
Dump tape is compressed.

关于如何恢复增量转储有什么建议吗?
