Backup Ends with Partial status code 1

[Yuvi]

from client Client: ERR - Cannot open file /directory/TSWORK.DBF . Errno = 22: Invalid argument

from client Client: ERR - Cannot open file /directory/TSWORKIDX.DBF . Errno = 22: Invalid argument

from client Client: ERR - Cannot open file /directory/C0000000.CAT. Errno = 22: Invalid argument

from client Client: ERR - Cannot open file /directory/C0000000.LRG. Errno = 22: Invalid argument

Even after configuring open file backup,these files are skipped and backup ends with partial in one client.

Kindly suggest me if it is required to backup or simply can be dropped.

Thanks

Yuvi..

Did you tried increasing client read time out  and check if it helps

try increasing verbosity of logs and set bpbkar enabled

[Yuvi]

checked with that settings it results the same.

Never try and backup db files while the database is online.

1) Use NBU plugin to backup the database
2) Use database utility to create backup to disk and then backup the disk backup with 'standard' policy (Unix/Linux clients) or MS-Windows (Windows clients)

Whichever method you choose, you need to create exclude_list on the client to exclude database files from normal backups. You can either add entire folder or wildcards, e.g.
*.dbf
*.cat
*.lrg
