== ShadowCopy ==
DRAFT HOWTO
==='''Overview'''===
This Howto is based on information contained in bug report
http://bugs.contribs.org/show_bug.cgi?id=1549
ShadowCopy takes a snapshot of ibays & user home folders at scheduled intervals and allows network users to restore previous versions of files via the Windows Explorer file properties page.
A client is installed by default in Windows XP.
To obtain a client for Windows 2000SP3+ download from here
http://technet.microsoft.com/en-gb/windowsserver/bb405951.aspx
This functionality is included in e-smith-samba, but requires further testing & verification
It requires e-smith-samba-1.14.0-20
sme7.3 has e-smith-samba-1.14.1-3.el4.sme
Please report any bugs to bugzilla, using this bug number http://bugs.contribs.org/show_bug.cgi?id=1549
==='''Configuration'''===
To check the installed rpm version
rpm -qa e-smith-samba
On a sme7.3 server this gives
e-smith-samba-1.14.1-3.el4.sme
so the installed rpm is more recent than that required (e-smith-samba-1.14.0-20)
Initially disable ShadowCopy for specific ibays or users you don't wish to take snapshots for
eg
db accounts setprop user1 ShadowCopy disabled
db accounts setprop user2 ShadowCopy disabled
db accounts setprop ibay1 ShadowCopy disabled
db accounts setprop ibay2 ShadowCopy disabled
Note: For the script to work correctly, leave two or more users enabled
Then enable and expand templates
config setprop smb ShadowCopy enabled
signal-event ibay-modify Primary
You need to schedule shadow copy to take snapshots.
You can do this manually from the command prompt
or run a cron job as often as required.
Snapshots are only taken if there are changes.
At the command prompt do
/etc/e-smith/events/actions/shadow-copy-rotate
Note: You will need enough free disk space to take a copy of the entire /home/e-smith/files directory plus any changes that take place.
A suitable cron job that runs the script every hour from 10am to 5pm on weekdays would contain the following:
Create a file
pico -w /etc/cron.d/shadowcopysnapshot
which contains
# Shadow Copy snapshot Crond Entry
#+-----------------------Minute (0-59)
#| +-------------------Hour of Day (0-23)
#| | +---------------Day of Month (1-31)
#| | | +-----------Month of Year (1-12)
#| | | | +-------Day of Week (0=Sun,6=Sat)
#v v v v v
00 10,11,12,13,14,15,16,17 * * 1,2,3,4,5 root /etc/e-smith/events/actions/shadow-copy-rotate
To save
Ctrl o
To exit
Ctrl x
After saving the above script do
/etc/init.d/crond restart
In Windows access the snapshot files via Windows Explorer file properties page, Previous Versions tab.
A Windows client exists in WinXP SP2
To obtain a client for Windows 2000SP3+ download from here
http://technet.microsoft.com/en-gb/windowsserver/bb405951.aspx
ShadowCopy files are located in:
/home/e-smith/files/.shadow/1
/home/e-smith/files/.shadow/2
/home/e-smith/files/.shadow/3
and so on...
The number of subfolders depends on how many snapshots have been taken.
Note that a new snapshot is only taken if files have changed.
