Topic: [BYPASSED] rsync backup and colon(:)

[globalsi]

Hi,

I have a problem to backup some files on my SME server.
I use rsync between my server and a cifs mount share.

All works usually but some files broke the process : files with colon ( : )
These files are email, created by SME :

Code: [Select]

[root@svrmail ~]# ls -ls  /home/e-smith/Maildir/cur/
total 3284

Can we ask SME to not create files dot instead of colon or semicolon or coma...?
Or how can I use ssh with this files ?

Thank for your help.

globalsi

first of all, what are you trying to achieve?
how? (the exact syntax)
why?

TIA

I want to backup emails of my server with versionning and easy restore.

I run this code every night :

Code: [Select]

/sbin/mount.cifs $IP_DISK_BACKUP $MOUNT_POINT -o credentials=/root/.smbcredentials,iocharset=iso8859-15 >> $LOG_FILE
/usr/bin/rsync -azh --stats --delete --backup --backup-dir=$FOLDER_HIST_DAY/ $FOLDER_ORIG $MOUNT_POINT/ >> $LOG_FILE
/bin/umount $MOUNT_POINT
IP_DISK_BACKUP, MOUNT_POINT, FOLDER_ORIG and FOLDER_HIST_DAY are variable defined in my script (for example : IP_DISK_BACKUP="//192.168.1.1/share")

Is it ok for you ?

TIA too

I use rsync to backup those files with a colon without an issue (through BackupPC). In which way the process is "broken" ? What error message do you have

[globalsi]

I think the problem come from cifs.
I have no problem with ssh between 2 servers without using cifs mount share.


The error is : the script is "as frozen" : nothing happen :  no more log, no more cpu consummation... I must kill it manually.

[Stefano]

just try to create, on the target machine, a file having the same structure/characters..

cifs share is on another linux machine or a windows one?

[globalsi]

Hi, it's a NAS (Fujitus Q700).

Finally, I've managed to establish a ssh connection between SME and the NAS with a key authentification.
So, I can rsync without a cifs share -> no more problem with colon.

The problem is bypassed (not solved).

[Stefano]

did you try to create a file on the target machine (on a cifs share) with a colon in filename?

I just tried and it doesn't work..

a little digging with google using "cifs filename colon" gives me many results.. it's not supported AFAICT

Yes, this why I asked if SME could not create files with colon or semicolon or coma...?

[Stefano]

this is not a SME's issue

No, it's a standard part of the maildir format.

cifs is broken. Avoid it.

Maybe you can tar or zip your data files into one archive, & then rsync the differences between the new archive on the server & the archive on your backup server/location/cifs mount.

ok, thank you

It's a possibility. thank you.
However, I've managed to solve it with full ssh.

[Jáder]

If you're using RSYNC why you need mount as CIFS ? Cannot you use pure SSH after enable it on web interface ?
I read spec here: http://www.ingrammicro.at/pdf/077TL01.pdf
And they include SSH and SFTP.
