Hi, colleagues. How ca create new variable for path bkp as PBS_REPOSITORY, etc...? I want bkp only last data file in folder:
Code: 
# ls /mnt/sqlbkp01/Fesapp/Day/
Fesapp.Day_2025-03-16.zip  Fesapp.Day_2025-03-24.zip  Fesapp.Day_2025-04-01.zip  Fesapp.Day_2025-04-09.zip
Fesapp.Day_2025-03-17.zip  Fesapp.Day_2025-03-25.zip  Fesapp.Day_2025-04-02.zip  Fesapp.Day_2025-04-10.zip
Fesapp.Day_2025-03-18.zip  Fesapp.Day_2025-03-26.zip  Fesapp.Day_2025-04-03.zip  Fesapp.Day_2025-04-11.zip
Fesapp.Day_2025-03-19.zip  Fesapp.Day_2025-03-27.zip  Fesapp.Day_2025-04-04.zip  Fesapp.Day_2025-04-12.zip
Fesapp.Day_2025-03-20.zip  Fesapp.Day_2025-03-28.zip  Fesapp.Day_2025-04-05.zip  Fesapp.Day_2025-04-13.zip
Fesapp.Day_2025-03-21.zip  Fesapp.Day_2025-03-29.zip  Fesapp.Day_2025-04-06.zip  Fesapp.Day_2025-04-14.zip
Fesapp.Day_2025-03-22.zip  Fesapp.Day_2025-03-30.zip  Fesapp.Day_2025-04-07.zip  Fesapp.Day_2025-04-15.zip
Fesapp.Day_2025-03-23.zip  Fesapp.Day_2025-03-31.zip  Fesapp.Day_2025-04-08.zip
Get full path file:
Code: 
# ls -dtr1 /mnt/sqlbkp01/Fesapp/Day/* | tail -1
/mnt/sqlbkp01/Fesapp/Day/Fesapp.Day_2025-04-15.zip
Use .bashrc for set this variable:
Code: 
function pathbkp_FesappDay() {
ls -dtr1 /mnt/sqlbkp01/Fesapp/Day/* | tail -1;
}
get path file:
Code: 
# pathbkp_FesappDay
/mnt/sqlbkp01/Fesapp/Day/Fesapp.Day_2025-04-15.zip
When use this variable get error:
Code: 
# proxmox-backup-client backup Fesappday.pxar:pathbkp_FesappDay
Error: unable to access 'pathbkp_FesappDay' - No such file or directory (os error 2)

that's not really a PBS question, but a shell question.. you need to actually call the function and pass its output/result to the proxmox-backup-client invocation. there's multiple ways to do it
- put it into a variable and use that when calling proxmo-backup-client
- call it inline using a subshell
- ..

hi, Fabian! Unfortunately variable not support in path for proxmox-backup-client backup <name>:<path>
Always result: Error: unable to access 'pathbkp_FesappDay' - No such file or directory (os error 2)

you need to call proxmox-backup-client using a shell, and let the shell expand the variable..
 
you are using a token, maybe you forgot to assign privileges to the token itself?

I need backup only one file. How i can do it? Folder backup OK, file, not...

Code: 
root@pbs01:~# proxmox-backup-client backup 1.pxar:/mnt/sqlbkp01/Fesapp/Day/Fesapp.Day_2025-04-16.zip --repository 'cifsbkp@pbs!backuptoken@localhost:PBS_Backup_sql_day'
Error: got unexpected file type (expected directory)

yes, I already told you how - you need to back it up as raw image file as a fixed index (fidx), not as a directory tree/pxar archive (didx). simply change the ".pxar" to ".img"
