Error: parse_rfc_3339 failed - wrong length at line 1 column 60 (500)

when do you get this error? can you post the content of the file /var/log/proxmox-backup/tasks/active ?
 
Hi i am sry but i make new vm for pbs to test it again it seems that backup was ok but with the log writing this had a problems the reason of error was this

INFO: Finished Backup of VM 105 (00:04:14)
INFO: Backup finished at 2020-09-27 12:36:13

but this comes only on local storage on nfs mounted storage was eveything fine -> now make a new vm without local backup storage only monted 2 nfs shares with 1 32 tb and 1 with 6 tb but weird they show as both 14,6gb each but test backup is fine no errors only the 300mb backup is greater now on pbs server they are now 800mb a question can we samba shares mount to or only nfs share?
 
ok now tryed a cifs share mounting and it is the same result with 14,6gb is showing me as the others same
 
here a refresh when i take this nfs shares directly from PVE all are ok they are with size correct from volume and the backup sizes back to normal to 300mb in this case on PBS they are 800 mb
 
what does 'proxmox-backup-client version --repository YOURBACKUPREPO' show ?
(where YOURBACKUPREPO is your repo + user e.g. root@pam@yourbackupserver:yourdatastore )
 
Hi it is all at latest state

AFAIU, you try to mount cifs/nfs as a base for your datastore but they all show the same usage?

can you post the output of 'mount' 'df -h' and the content of /etc/proxmox-backup/datastore.cfg ?
 
Hi mate,
first many thx for your quick renponses.Yes exactly thoose errors are only on local storage on nfs or cifs shares all work fine so i decide to mount thoose drives for test to try. Just for testing how PBS is. Thoose drives are 32TB nfs share for my backups.

as you see VM-BACKUPS is 2 times there one for NFS and the other for CIFS share to try mybe it works.

many thx

actually those are not cifs/nfs mounts

the datastore path is always local since using local storage is the primary (and recommended) way
if you want to use nfs/cifs for a datastore, for now you have to manually mount them (or put them in a mount-unit/fstab) and select that path
pbs will not mount any nfs or cifs for you
 
Ok many thx. Well local storage make this errors, as on PVE NFS works i tryed to mount NFS share to test it on PBS. but it worked on 1st installation now on 2nd installation this not works. Weird is same backup on PVE makes around 300mb data and on PBS it was 800mb i thing the compression is much other on PVE was ZSTD but on PBS you can not change it, is greyed out, but a huge difference it is around 2,5 times bigger the same vm backup.
On the otherside you have on PBS even not way to remove the added datastores. Well thing this need more improved for now. Will give a try on later time again. Many thx for help

the log does not seem to have the same issue so i doubt it is the same problem

pbs did never mount any nfs or cifs automatically, if it worked, it would have some other reason

pbs backups are by default compressed with zstd. not the whole archive as one part but as chunks. that can be the reason why a single backup is bigger than the default vzdump. the advantage is that only the different chunks on the following backups are using additional storage, so if you have 10 backups, pbs might very well use less space than 'old-style' vzdump backups
 
Hello,

I'm having the exact same issue as the OP. Backups were working until I updated recently, I want to say 5 days ago.

I have a Synology NAS CIFS share mounted to a vm running proxmox backup server. The share is automounted via fstab. The entry looks like this:
//nas-01/pbs /mnt/nas-01/pbs cifs credentials=/root/.nas-01.auth,uid=34,gid=34 0 0

UID/GID 34 are the backup user on this system, which appears to run the proxmox backup server processes.

The mount looks like this:
//nas-01/pbs on /mnt/nas-01/pbs type cifs (rw,relatime,vers=3.1.1,cache=strict,username=pbs,uid=34,forceuid,gid=34,forcegid,addr=10.10.10.60,file_mode=0755,dir_mode=0755,soft,nounix,serverino,mapposix,rsize=4194304,wsize=4194304,bsize=1048576,echo_interval=60,actimeo=1)

As I mentioned, backups were working fine up until 09/24. When backups run now, they appear to run and complete, and then fail on the upload log step.

hmm after looking at the code, i honestly do not know how this error could pop up in such a way...
do you get an error when looking at the task list in the pbs gui?
 
I do not get any errors frm either the Proxmox task view or the Proxmox Backup Server task view. I'm going to install a bare metal device today with Proxmox Backup Server with physical drives instead of CIFS and see if I get the error on that install also.

EDIT: I just noticed something from this attempt. While there's an error on the Proxmox Cluster side, from the Proxmox Backup Server side there is no indication of an error, and a backup is listed in the VM Backup Group section. Unfortunately what's listed fails to restore.

From the PVE Task:
Error: parse_rfc_3339 failed - wrong length at line 1 column 60 TASK ERROR: command '/usr/bin/proxmox-backup-client restore '--crypt-mode=encrypt' '--keyfd=13' vm/101/2020-09-30T13:22:13Z index.json /var/tmp/vzdumptmp1607236/index.json --repository root@pam@pbs:nas-01' failed: exit code 255

There was nothing on the PBS server to indicate that a restore was event attempted.

One a side note, it would be nice when restoring to restore to a different VMID

So, I installed PBS onto a machine by itself with a local ZFS pool. Added it as a storage source to my PVE cluster. I backed up a single VM, it ran without error.
