Dotaz: Problem obnovy cez rdiff-backup

[jojo]

Ahojte..Mam problem obnovit cez rdiff-backup na Debiane na vps ( xen )

Zalohujem prikazom

rdiff-backup --exclude-other-filesystems / root@10.0.0.1::/home/zaloha ( / preto aby zalohovalo vsetko okrem --exclude )

Zaloha sa bez problemu ulozi na vzdialeni server tiez bezi na VPS ( xen ) Debian.

Obnovujem prikazom

rdiff-backup -r now --force root@10.0.0.1::/home/zaloha / ( / takisto aby obnovilo vsetko ,ked nedam force vypise chybu )

Potom mi vypise na masine kde obnovujem chyba

Problém je:

OSError: [Errno 39] Directory not empty: '/dev/.udev'

Prečo zálohuješ /dev/ ? Skús tento adresár vynechať.

/usr/bin/rdiff-backup --exclude /tmp --exclude /mnt --exclude /proc --exclude /dev --exclude /cdrom --exclude /floppy server1_backup::/ /backup/server1

NEPOMOZE, aj ked vynecham /dev .... takisto chyba

Teraz je problem v inom adresari (na konci vypisu):

OSError: [Errno 16] Device or resource busy: '/lib/init/rw'

Tento adresar by si mal tiez vynechat, jedna sa o docasne ulozisko (tmpfs) pri boote systemu. Pravdepodobne si tentokrat zabudol na --exclude-other-filesystems.

[jojo]

Takisto chyba pri obnoveni iked davam zalohovat s vynechanim to iste aj obnovenie --exclude-other-filesystems

Fatal Error: Lost connection to the remote system

[wike]

Problém je, že bolo prerušené spojenie so serverom:

Fatal Error: Lost connection to the remote system

Skontroluj si teda pripojenie a skús to znova.

[jojo]

Ved jasne lebo nejaka chyba a spojenie padne, inak je spojenie ok

[wike]

Tá "nejaká" chyba má takýto popis:

exception KeyError
Raised when a mapping (dictionary) key is not found in the set of existing keys.

Môže to byť teda spôsobené čímkoľvek. Napríklad tým, že bolo prerušené spojenie a nedá sa získať ďalší súbor na vzdialenom stroji pre porovnanie.

Mohol by si skúsiť BackupPC, má jednoduchšie (web) rozhranie.

backuppc som skusil ale ten zase neviem nakonfigurovat, ako tak s rdiff-backup viem ale backuppc neviem...nakonfigurovat ho aby zalohovalo kompletne cely disk,lebo ked po instalacii sa pripojim na stranku backuppc tak mam na vyber v menu localhost ale nejako nic sa nedeje, ziadny dobry navod som nenasiel ..
