[SOLVED] backup to new datastore

[Dzung]

Hello!
I error on old datastore

Oct 18 15:34:18 backup proxmox-backup-proxy[977]: starting new backup on datastore 'Backup': "vm/8110/2021-10-18T08:34:17Z"

so I want to create new datastore to backup but I got error " 400 Bad Request: no valid previous backup"

Oct 18 23:48:57 backup proxmox-backup-proxy[1144]: TASK ERROR: backup ended but finished flag is not set.

anyone help me how to create backup on new datastore

 

[dcsapak]

the real error is in both cases:

POST /fixed_index: 400 Bad Request: unable to get shared lock - EIO: I/O error

please tell us a bit more about your setup and storage? anything in dmesg during the backup?
