couchdb-backup-restore problem with some dbs

[Wojciech Matys]

Hello,

I'm searching for tool for backups and restoration for BigCouch (kazoo cluster). First
tool which really worked for me was:

https://www.npmjs.com/package/couchdb-backup-restore

but I have problems with some dbs. Currently my BigCouch consist 23 dbs and I have a problem
with restoration 3 of them:

account/30/ac/c1da150424bb242f2341240b13d0
account/9c/91/e35f7958fd05c7e608108cd1c530
system_media

where I'm getting:

all other dbs were restored from backup without any problems - any suggestions?
